Alumni Establish Matching Fund for

K-12 STEM Teachers THE FUND WILL SUPPORT SCHOLARSHIPS FOR UC DAVIS TEACHING CREDENTIAL STUDENTS WHO HAVE THE INTEREST, PASSION, AND APTITUDE TO TEACH STEM-RELATED SUBJECTS...

IN CALIFORNIA, the predicted demand for professionals in science, technology, engineering, and math (STEM) fields will grow nearly 20 percent by 2018. Yet too few students are choosing STEM fields. UC Davis alumni Nancy (’74, Cred ’75) and Tom Patten (Civil Engineering ’74, MS ’76) believe enthusiastic and well-prepared teachers are the key to unlocking the state’s potential for innovation and prosperity. To help train the next generation of STEM teachers, the Pattens have pledged $100,000 to establish a new matching fund for the Next Generation STEM Teaching Award. The fund will support scholarships for UC Davis teaching credential students who have the interest, passion, and aptitude to teach STEM-related subjects in K-12 public schools. By preparing educators to inspire the next generation of students to pursue STEM majors and careers, UC Davis strengthens California’s and the nation’s ability to tap the true potential of its future innovators.

A SHOP FOR

DREAMERS

Nuts and Bolts Come Together in the College of Engineering’s Fabrication Lab UC DAVIS STUDENTS were

pleasantly surprised, when returning to the Engineering Fabrication Lab (EFL) for the fall quarter. This popular “engineering workshop,” located in 1220 Bainer Hall, was upgraded with all sorts of cool new equipment during the summer. The lab has been augmented with three DMG Mori machining centers; an OMAX 5-axis waterjet; a Trotec Speedy 400 laser engraver and cutter, for plastic and wood; a ShopBot Buddy with 12-inch Z-axis; three Miller MIG/TIG welders and two precision welding layout tables; upgraded fume extraction for the welding area; four Bridgeport knee mills; three Harrison lathes; two Ultimaker Extended 3D printers; a PCB prototyping area with mill, semi-auto pick-and-place, and reflow oven; a Baileigh powered tubing bender and notcher; 10 CAD/CAM workstations; and four electronics workstations with a full complement of pro-grade soldering and rework tools. The new equipment was acquired thanks to a a generous educational discount from DMG Mori, and financial support from the College of Engineering. The equipment upgrades are the first visible step in an ambitious, multi-phase renovation, expansion and reconfiguration of Bainer Hall’s north wing, ultimately leading to the creation of a new Engineering Student Design Center (ESDC).

College leadership evaluated the future needs of engineering students to develop a list of desired equipment. “We knew what’s currently available in industry, and we knew some of the trends,” explains Mike Akahori, manager of the EFL. “We asked students and grad students what they needed or wanted; we also visited other universities, to see what they were buying and using.” The EFL currently runs eight labs at a time: four mechanical and four biomedical. “We also support a series of small ancillary labs for various departments,” Akahori notes, “like our engine lab, where students disassemble a gasoline engine, and then put it back together so that it runs again. We also have short-course labs for civil engineers and chemical engineers.” “The best part, as we’re able to accommodate increased demand for hands-on opportunities is the improved collaborative atmosphere. Students from different majors will be able to work together on a single project. It’ll be a great think tank.” Nurturing that innovative spirit is what makes Akahori’s “play space” so important. “Students get into engineering to embrace the creative part of their career path,” he smiles, “and this is where they can get their first taste of such experience. A lot of today’s students are dreamers, and the EFL is a vehicle for achieving those dreams.” EE NN GG I NI N EEE RR I NI N G GP P RR OO GG RR EE S S S/ /S uWmi nmt e r 2 0 1 6 5 5

Grant for natural hazards research at

UC DAVIS CENTRIFUGE THE NATIONAL SCIENCE FOUNDATION will award almost $5 million over five years to UC Davis to include the large earthquake-simulating centrifuge at the Center for Geotechnical Modeling as part of the new Natural Hazards Engineering Research Infrastructure program. The center operates a nine-meter (30-foot) radius centrifuge with a shake table, the largest of its kind in the world. Researchers can build complex models of soils and structures on the shake table, fit them with instruments and sensors, and shake them while they rotate on this massive machine. This allows accurate scale-model studies of soils and soil-structure systems such as buildings and foundations, near-shore and off-shore energy infrastructure foundations, underground structures, pipelines, ground improvement technologies, wharves, embankment dams, and levee systems. The grant will support research operations at the center over the next five years, making it available to NSF-funded researchers nationwide as well as at UC Davis. The research performed will enable major advances in the ability of engineers to predict and improve the performance of soil and soil-structure systems affected by earthquake, wave, wind, and storm surge loadings. The Center for Geotechnical Modeling, housed in the UC Davis Department of Civil and Environmental Engineering, has operated the large centrifuge as a unique, shared national resource for more than 30 years. The facilities have been used by researchers from the Universities of California (Davis, Berkeley, Los Angeles, San Diego, and Irvine), Colorado, Texas, and Washington; Oklahoma State; Arizona State; Oregon State; Virginia Tech; and Tokyo Institute of Technology, among others.

New technology will help define the environmental triggers of childhood asthma UC Davis researchers receive funding to develop a wearable sensor device UC DAVIS RESEARCHERS have received a four-year, $1.5 million grant from the National Institutes of Health (NIH) to develop a small, wearable sensor that can measure the relationship between environmental exposures and pediatric asthma. The hope is that the device will lead to new treatment options for the more than 5 million children in the U.S. who have asthma, a chronic, inflammatory lung disease that restricts breathing and is a significant cause of hospital visits and missed school days. “Asthma is more common and harder to control in regions with high pollution levels, but we don’t know the specific chemicals that trigger it,” said co-principal investigator Nicholas Kenyon, chief of pulmonary, critical care and sleep medicine at UC Davis and a specialist in difficult-to-treat asthma. “The new device helps by providing detailed, real-time data on the occurrence of bronchospasms in relation to environmental exposures.” Co-principal investigator Cristina Davis, professor of mechanical and aeronautical engineering, worked with Kenyon to develop and test initial components of the device, which combines lung-function with breathmeasurement and chemical-sensing technologies. Their initial work was funded by The Hartwell Foundation, UC Davis Clinical and Translational Science Center (CTSC) and the National Science Foundation. The new grant — part of the NIH’s Pediatric Research using Integrated Senor Monitoring Systems, or PRISMS, Program — allows the team to integrate the technology into a form no larger than a pen that can be easily worn in the pockets of children. Once developed, the device will be pilot tested to determine its clinical potential. “We are creating a critical tool in finding the ‘missing links’ in our understanding of asthma,” said Davis. “If we can identify the source and components of chemicals that lead to pulmonary exacerbations, we are well on our way to policy changes and treatments that protect children.” In addition to Kenyon and Davis, researchers on the UC Davis grant are Robin Steinhorn, senior vice president of hospital-based specialties at Children’s National Health System; and Michael Schivo, assistant professor of pulmonary, critical care and sleep medicine at UC Davis.

Ready for Her Close-up JENNIFER SINCLAIR CURTIS EMBRACES HER ROLE AS NEW DEAN By Derrick Bang

“WE NEED TO BE BETTER ABOUT SPREADING THE NEWS THAT UC DAVIS IS LADEN WITH GREAT TALENT AND ACHIEVEMENT!” – JENNIFER CURTIS

JENNIFER CURTIS HIT THE GROUND RUNNING, when she arrived at UC Davis in late October. “I thrive on being busy,” she smiles, “and I have lots of plans.” Curtis, who became Dean of the College of Engineering that month, is quite impressed by what she’s found at her new academic home. “The raw power of the college’s faculty, and their level of creativity, are unbelievable. People are warm and collaborative, and they’re passionate about their work. They’ve also been recognized to an impressive degree: We have more national academy members, as a percentage of total faculty, than a number of the Top 10 schools. “We need to be better about spreading the news that UC Davis is laden with great talent and achievement!” Curtis comes to UC Davis following an 11-year tenure at the University of Florida’s College of Engineering, where she rose to Associate Dean for Research and Facilities after serving as Chair of the Department of Chemical Engineering. Her numerous executive responsibilities in the Sunshine State included a role as Director of the Florida Energy Systems Consortium, an energy research collaboration involving all 12 of Florida’s state universities. Curtis completed her undergraduate work in chemical engineering at Purdue University, and earned her PhD in the same field at Princeton. An initial academic position at Carnegie Mellon University was followed by a return to Purdue, where — as Associate Dean of the College of Engineering — she helped launch a new Department of Engineering Education: the first in the U.S. As a researcher, she is recognized for her pioneering work in the development of numerical models for the prediction of particle flow phenomena. The importance of her research has been validated, over time, via multi-year funding from major corporations such as Alcoa, Chevron, Dow, DuPont and Pfizer. At UC Davis, she’s ready to embrace structure, organization and strategic planning. “I want to get all the pieces aligned, so we’re all moving in the same direction: toward large initiatives that will bring us even more national visibility.” Curtis has devoted her career to enhancing the reputation and diversity of the next-gen engineering pool, and she’s eager to channel that energy toward UC Davis.

“Consider industry internships,” she suggests. “There’s a sense that we don’t have enough students participating, possibly because they’re not aware of the wide range of internships and jobs that are available. We need to get that message across from the moment students arrive on campus, so I’d love to see a seminar course that brings in working professionals every week, to share their views on getting connected, and the mechanics of seeking out internships. “On a similar note, industry frequently tells academia that students who embrace study abroad programs, who are willing to climb out of their comfort zones, are destined to be future leaders. And yet, right now, too few of our engineering students participate in study abroad programs. We need to develop methods that will further encourage student participation. “We know that our students are outstanding technically, but I want to make sure that they gain leadership skills, and see themselves as global citizens. “I’d also like to develop a certificate program in leadership and expand the existing technology management minor program so students can obtain this type of knowledge to supplement their

engineering degrees. I look forward to partnering with the Graduate School of Management to help develop and improve these skills in our students and faculty.” Curtis points with enthusiasm to the College of Engineering’s recent entrepreneurial initiatives, such as the Engineering Student Startup Center (ESSC), the Dorf Design and Communications Classroom, and expansion plans for the college’s Engineering Fabrication Lab. “Our entrepreneurial training is terrific, and the participating students love it just as much as our corporate advisory board members,” Curtis acknowledges. “However, the number of students served remains a small fraction of our undergraduate base. All these things are successful, but we need to scale them up, and to engage all of our freshmen.” She understands that these goals would require a greater time commitment by faculty, since such interactive courses will be more like hands-on lab research. “The size of the College is important, and we’re hiring 15 new faculty this academic year alone. Five years from now, I’d like to see a 15- to 20-percent growth, to bring our faculty to between 230 and 240. That’ll also achieve our goal of improving the faculty/ undergraduate ratio, to decrease the number of students per professor, so we become commensurate with our peers. “That also means adding to the infrastructure and facilities for education and research, so I plan to be very involved with our development efforts.” Curtis also recognizes the crucial importance of high-profile research work. “We’ve had several big wins during the past few months,” says Curtis, citing the $15.5 million National Institutes of Health Transformative Research Award to build the world’s first total-body PET scanner; the collaborative $18.5 million National Science Foundation Engineering Research Center grant, which will partner UC Davis in a new Center for Bio-inspired and Bio-mediated Geotechnics; and a $5 million National Science Foundation award to the UC Davis Center for Geotechnical Modeling as part of the National Hazards Engineering Research Infrastructure (NHERI) program. Bringing the world to the UC Davis College of Engineering clearly is a top priority for Curtis. “I want to hire proposal consultants, who will work alongside faculty from the very beginning of a research pitch: to help with teambuilding and visioning, through the entire process. I had great success with this at the University of Florida, and there’s no question that we’ll get many more submissions if our UC Davis faculty know that the college will support them during such large-scale proposal initiatives. “When we win, it’s huge research dollars, and it’s also an outstanding educational opportunity for our students. “And, best of all, research awards validate our talented faculty, bringing great credibility and prestige, which gains huge visibility for our College of Engineering.”

GEOTECHNICAL ENGINEER JASON DEJONG EXPLORES “BIO-SOIL” AS A MEANS OF STABILIZING FUTURE DAMS, BRIDGES AND BUILDINGS By Derrick Bang

JASON DEJONG, a professor in the UC Davis Department of Civil and Environmental Engineering, operates in a field — geotechnical engineering — that is (in)famous for its elusiveness. “Geotechnical engineers don’t make cars or computers,” he laughs. “We don’t even work with known materials such as steel. I go to a site where a dam must be built, and I examine the material beneath. Do I need to improve it? Replace it? Or can I live with it, and build on top of it? Then what will it do? “I like the uncertainly and ambiguity of soils and geotechnical engineering. I like the fact that after we do all the calculations, and believe we understand everything, uncertainties still exist. So we have to step back and consider the likelihood of possible outcomes, and balance that against a responsibility to build civil structures that will be safe for society.” DeJong earned his bachelor of science in civil engineering, with high honors, from UC Davis. He earned both his master’s degree and doctorate at the Georgia Institute of Technology. After research assignments in the oil and gas industries in Western Australia and Norway, he joined UC Davis in 2005. Since then, DeJong has become a mover and shaker in two distinct areas of his field: dam analysis, to determine structural integrity; and the development of an innovative, biologically enhanced method of improving a construction site’s pre-existing ground conditions. Between the two, he has secured five National Science Foundation grants. ­12 U C D AV I S C O L L E G E O F E N G I N E E R I N G

Most recently, he embraced a leadership role in the creation of a new U.S. geotechnical engineering center. UC Davis, Arizona State University, New Mexico State University and the Georgia Institute of Technology have joined forces to create the Center for Bio-inspired and Bio-mediated Geotechnics (CBBG), to expand the rapidly emerging field of biogeotechnical engineering. The National Science Foundation (NSF) will support this new center with a five-year, $18.5 million grant: the nation’s largest single investment in geotechnical research. DeJong will head the UC Davis team. Back in 2006, his lab published the first peer-reviewed journal article that demonstrated how bio-mediated processes could improve the solidification of loose sands: one of the key geotechnologies within this new ERC. “In many respects,” he notes, “the technical content of the Center proposal built heavily on the work performed by our UC Davis research group.” The basis for the CBBG also derived heavily from “white papers” that emerged from international workshops co-led in 2007 and 2011 by DeJong and Kenichi Soga, a professor of civil engineering at the UK’s University of Cambridge. DeJong also remains heavily involved in a massive endeavor to analyze dams throughout the state of California, a project that gained even more urgency following the Richter-6.0 earthquake that struck South Napa in August 2014. As it happens, many of California’s large dams were built on old river channels composed of gravel and sand, which can liquefy

And we finally succeeded.” The result, dubbed an Instrumented Becker Penetration Test, could become an industry standard. But analysis is only part of the equation. If a dam is deemed unsafe, can it be made stable by means that are less expensive and cumbersome than starting over, at some geologically superior location? DeJong began exploring this aspect of his field back in 2003, as a result of his interest in ground improvement: the need to enhance pre-existing soil conditions that are insufficient to provide the desired performance at a construction site. “Either the soil will settle, or it’ll slip and fail,” he explains. “We go in and improve the ground. Historically, this has been driven by people in industry and construction; they’ll inject g rout, cement, silic ate s, epox y or something else. Or they’ll vibrate the heck out of it, to densify it. Either way, it’s a high-energy, high-carbonfootprint, brute-force tactic. “I wondered if there might be a subtler, more optimized alternative.

UC Davis Receives $15.5 Million for

Breakthrough PET Scanner A RESEARCH TEAM AT UC DAVIS is set to build the world’s first total-body positron emission tomography (PET) scanner: a device that could fundamentally change the way cancers and other diseases are diagnosed and treated. Thanks to a five-year, $15.5 million Transformative Research Award from the National Institutes of Health (NIH), the team will be able to build a full-size prototype, which could put the university on the nation’s leading edge of molecular imaging. The EXPLORER project — led by Simon Cherry, a distinguished professor of biomedical engineering; and Ramsey Badawi, a professor of radiology — has been in the works for 10 years. The NIH award arrives at a time when technology has caught up with the vision, making it possible to efficiently process all the data generated from the half a million detectors needed for a total-body scanner. “This could be a total game-changer,” said Ralph de Vere White, director of the UC Davis Comprehensive Cancer Center. “If this works, it will change medicine. It will change cancer detection, and how we evaluate therapies.” “The vision is to solve two fundamental limitations of PET, as currently practiced,” said Cherry. “The first is to allow us to see the entire body all at once. The second huge advantage is that we’re collecting almost all of the available signal, which means we can acquire the images much faster, or at a much lower radiation dose. That’ll have some profound implications on how we use PET scanning in medicine and medical science.” Cherry and Badawi predict that by seeing the entire body simultaneously, their scanner could drop the radiation dose by a

factor of 40, or decrease scanning time from 20 minutes to just 30 seconds. A quicker scan also could reduce the incidence of images blurred by patient movement, resulting in images with more detail. The technology would have implications in diagnostics, treatment and also drug development. With whole-body PET, physicians could diagnose a disease and then follow its trajectory in a way never before possible, and which could affect how patients are treated. This approach reflects the current trend in medicine: to develop systems-based treatments and more individualized care. Cherry and Badawi are joint principal investigators. The team also includes Jinyi Qi, a professor of biomedical engineering, who leads the computational aspects of the project; and Terry Jones, a volunteer clinical faculty in diagnostic radiology, who has developed some of the key potential biomedical applications for the scanner, and will be directly involved in planning the early uses of the EXPLORER technology for human imaging studies. The project is a consortium led by UC Davis, which also involves researchers at the University of Pennsylvania (led by Joel Karp) and Lawrence Berkeley National Laboratory (led by William Moses). Down the road, the team hopes to see the technology commercialized, ultimately making it available to hospitals and researchers worldwide. “This is the project of my career, no question,” Cherry said. “It’s an amazing privilege and responsibility to work on something of this scale, which has the potential to have so much impact in biomedical research and health.”

Helping Growers Optimize Irrigation Technology developed at UC Davis is giving growers tools to help irrigate more effectively UC DAVIS biology and agricultural engineering professor Shrini Upadhyaya and his team designed a sensor that attaches to a single leaf to measure temperature, light, wind, and humidity to help optimize plant irrigation. The key to effective irrigation is giving crops the right amount of water in the right place at the right time. Easier said than done, but new technology developed at UC Davis is giving growers a convenient way to find that sweet spot. “Now growers don’t even have to go to the field to decide when, where, and how much to irrigate,” said Shrinivasa Upadhyaya, a UC Davis professor of biological and agricultural engineering. “We developed a suite of sensors that delivers real-time plant-stress data to your computer or mobile device.” The technology is now available from Cermetek Microelectronics in a device called LeafMon, designed for vineyards and almond and walnut orchards. As the research expands, more crops may come online. Frank Stempski, sales manager for the Milpitas-based company, says LeafMon will help growers save water Shrini Upadhyaya (R) and Gallo Winery research scientist Luis Sanchez (L) in a vineyard and improve crop quality and yield. where a research team is conducting tests with the sensor. “The goal is to keep crops in near ideal conditions, at all times,” Stempski said. Traditionally, growers have irrigated on a schedule tied to weather conditions. More recently, soil sensors have helped growers water only when their soil is dry. But that can be misleading. “Just because soil is dry near the surface, doesn’t mean plants are suffering,” Upadhyaya explained. “And just because soil is moist, doesn’t mean plants are happy. Orchard and vineyard crops have “NOW GROWERS DON’T extensive root zones, so sensing moisture at a certain depth doesn’t guarantee the plant can access that water.” EVEN HAVE TO GO UC Davis researchers helped develop pressure chambers to provide a more accurate read by gauging how hard a plant is working to pull moisture from the soil.

Luis Sanchez, senior research scientist with E&J Gallo Winery, says the sensor could also work well in tandem with other high-tech irrigation scheduling methods based on remote sensing. “It could be a very useful tool for verifying our satellite-based irrigation schedules,” Sanchez said. “The plant-stress sensor system could help us fine-tune our irrigation to improve crop quality and yield.” E N G I N E E R I N G P R O G R E S S / S u m m e r 2 0 1 5 15

Nanoporous gold sponge makes

PATHOGEN DETECTOR By Jocelyn Anderson

SPONGE - LIKE NANOPOROUS GOLD could be key to new devices to detect disease-causing agents in humans and plants, according to UC Davis researchers. In two recent papers in Analytical Chemistry, a group from the UC Davis Department of Electrical and Computer Engineering demonstrated that they could detect nucleic acids using nanoporous gold, a novel sensor coating material, in mixtures of other biomolecules that would gum up most detectors. This method enables sensitive detection of DNA in complex biological samples, such as serum from whole blood. “Nanoporous gold can be imagined as a porous metal sponge with pore sizes that are a thousand times smaller than the diameter of a human hair,” said Erkin Şeker, assistant profe s sor of elect r ic al and computer engineering at UC Davis and the senior author on the papers. “What happens is the debris in biological samples, such as proteins, is too large to go through those pores, but the fiber-like nucleic acids that we want to detect can actually fit through them. It’s almost like a natural sieve.” Rapid and sensitive detection of nucleic acids plays a crucial role in early identification of pathogenic microbes and disease biomarkers. Current sensor approaches usually require nucleic acid purification that relies on multiple steps and specialized laboratory equipment, which limit the sensors’ use in the field. The researchers’ method reduces the need for purification.

­16 U C D AV I S C O L L E G E O F E N G I N E E R I N G

“So now we hope to have largely eliminated the need for extensive sample clean-up, which makes the process conducive to use in the field,” Şeker said. The result is a faster and more efficient process that can be applied in many settings. The researchers hope the technology can be translated into the development of miniature point-of-care diagnostic platforms for agricultural and clinical applications. “The applications of the sensor are quite broad ranging from detection of plant pathogens to disease biomarkers,” said Şeker. For example, in agriculture, scientists could detect whether a certain pathogen exists on a plant without seeing any symptoms.

UC DAVIS COLLEGE OF ENGINEERING JOINS EDUCATION INITIATIVE

RICARDO CASTRO EARNS CALORIMETRY AWARD

The UC Davis College of Engineering has partnered with 121 other U.S. engineering schools, in an effort to spearhead a transformative movement in engineering education. In a Letter of Commitment presented to President Obama on March 23, 2015, during the fifth annual White House Science Fair, the UC Davis College of Engineering and its peer institutions promised to establish and enhance special education programs designed to better prepare undergraduates for solving the world’s so-called “Grand Challenges”: the complex, yet achievable goals necessary to improve health, security, sustainability and quality-of-life issues in the 21st century. “We at UC Davis have recognized the need for a design-centric educational program that engages engineering students in learning leadership, social, entrepreneurship and global skills, and how these skills are applied in solving grand challenges,” noted Enrique J. Lavernia, former dean of the College of Engineering, in his own letter to President Obama. Each of the 122 signatory schools has pledged to graduate a minimum of 20 students per year, who have been specially prepared to lead the way in solving such large-scale problems, with the goal of training more than 20,000 formally recognized “grand challenge engineers” during the upcoming decade. “Our Grand Challenges for Engineering already have inspired more and more of our brightest young people to pursue careers that will have direct impacts on improving the quality of life for people across the globe,” said NAE President C.D. Mote Jr. “Imagine the impact of tens of thousands of additional creative minds, all focused on tackling society’s most vexing challenges. ‘Changing the world’ is not hyperbole, in this case. They’ll do it ... and they’ll inspire others, as well!”

The North American Calorimetry Conference (CALCON) has presented its 2015 James J. Christensen Award to RICARDO CASTRO, an associate professor in the UC Davis Department of Chemical Engineering and Materials Science. The award includes an honorarium of $1,000. Castro delivered a keynote lecture at the 70th Ricardo Castro International CALCON, which took place July 12-16, 2015, in Baltimore, Maryland. Since its inception in 1945, the North American Calorimetry Conference has served as the premier collegial forum for the dissemination of current research and stateof-the-art technological developments in calorimetry and thermodynamics. The Christensen Award was established in 1988, to honor Brigham Young University’s Prof. James J. Christensen (1931-87). The award is presented to a scientist who has made outstanding innovative contributions to the development and use of calorimetric instrumentation: the science of measuring the heat developed during a mechanical, electrical or chemical reaction, and of calculating the heat capacity of materials.

DEBBIE NIEMEIER RECEIVES GUGGENHEIM FELLOWSHIP The John Simon Guggenheim Memorial Foundation has awarded one of its prestigious Guggenheim Fellowships to DEBBIE NIEMEIER , a professor in the UC Davis Department of Civil and Environmental Engineering. The Fellowships, sometimes regarded as “midcareer awards,” are presented to individuals who’ve demonstrated an exceptional capacity for productive scholarship. Roughly 200 Fellowships are awarded each year, from a field of between 3,500 and 4,000 applications. Recipients are encouraged to spend the cash portion of their award as they see fit, since the goal is to provide Fellows with “blocks of time in which they can work with as much creative freedom as possible.” Niemeier’s research interests span transportation, vehicle emissions and air quality monitoring; energy consumption and land use interactions; and public sector infrastructure programming and budgeting. She was a member of the independent review teams assigned to assess the cost increases in the construction of the new San Francisco Bay Bridge, and to review the cost methods employed for the proposed third locks of the Panama Canal. As part of a company formed with three former students, she also works with legal advocacy groups around the world, on social justice issues associated with access to transportation and related air quality.

by Jae Wan Park, an associate professor in the UC Davis Department of Mechanical and Aerospace Engineering. The project, titled “Demonstration of Community-Scale, LowCost, Highly Efficient PV and Energy Management System,” received a grant of $1.24 million. The project addresses the major challenges faced as our nation attempts to increase its reliance on solar power: the intermittent nature of solar generation, and resulting grid instability; the imbalance between energy demand and production; and the expense of existing energy storage models. Park and his team plan to develop a smart electrical energy storage (EES) and management system that could reduce a community’s daily average energy demand, during peak times, by up to 87 percent. The system will be tested at UC Davis’ Robert Mondavi Institute for Wine and Food Science, which already employs 120 kW of photovoltaic (PV) panels and an 800 kW diesel generator, and plans to add an additional 100 kW of PV panels and 250 kWh of EES units that will utilize second-life lithium ion batteries. Park joined the UC Davis College of Engineering in September 2008. He is director of the UC Davis Green Transportation Laboratory, the U.S.-South Korea Transportation Study Program at the campus’ Institute of Transportation Studies, and the UC Davis Formula Hybrid Racing Team. His research interests include green energy systems with batteries and proton exchange membrane (PEM) fuel cells.

CHEEMENG TAN EARNS LIFE SCIENCES FUNDING AWARD The International Human Frontier Science Program (HFSP) has presented one of its 2015 Young Investigator Grants to CHEEMENG TAN , an assistant professor in the UC Davis Department of Biomedical Engineering. The project, a collaboration between Tan and Michael Nash — a professor in the Department of Biophysics and Molecular Materials at Ludwig-Maximilians University, in Munich, Germany — is titled “Unraveling Dynamical Coupling Between Gene Expression and Cellulosome Assembly.” Tan and Nash will share $250,000 per year for the three-year project, which integrates synthetic biology, microfluidics and singlemolecule imaging for the study of cellulosome assembly. Cellulosomes are protein networks used by anaerobic bacteria to digest cellulosic biomass. The protein networks consist of subunits that are held together by receptor-ligand pairs, some of which have similar affinities to the same binding sites. It currently remains unclear how cells modulate the assembly of cellulosomes, because studies are hampered by a lack of tools to manipulate genetic compounds of native cellulosome-producing bacteria. In order to resolve these issues, studies of cellulosome assembly require nanoscale measurement methods. Tan joined the UC Davis College of Engineering in August 2013. His research interests include the engineering of artificial cellular systems, novel strategies of antibiotic treatment, and the underlying mechanisms of cellular heterogeneity. His Artificial Cellular Systems Group focuses on the engineering of synthetic biological systems for therapeutic treatment.

CHEMICAL ENGINEERING STUDENTS TAKE TOP PRIZE A TEAM OF STUDENTS from the UC Davis Department of

Chemical Engineering and Materials Science won first place in the Chem-E-Car competition, one of several contests held at the American Institute of Chemical Engineers’ (AlChE) 2015 Western Student Regional Conference, held April 24-25, 2015, at Cal Poly Pomona. This first-place victory qualified the Aggie engineering team to move forward and compete at the upcoming AlChE Annual Meeting, which will take place Nov. 8-13 in Salt Lake City, Utah. Chem-E-Car is an AlChE competition that challenges university students to design and construct a shoebox-sized car powered solely by a chemical energy source; the vehicle must safely carry a specified load over a given distance, and then stop as close to the assigned range as possible. The UC Davis team was led by Chris O’Connor, Nick DiPressi, Amy Ly and Jordan Provost. More than 40 student engineers participated in the design and construction of their team vehicle, dubbed “Leadfoot.” When the dust had settled, Leadfoot’s run of 19.54 meters came closer to the goal — by roughly 2 meters — than any other competitor.

ECE STUDENTS WIN MODEL

CAR COMPETITION A TRIO OF UNDERGRADUATES in the UC Davis Department of Electrical and

Computer Engineering (ECE) — Andrew Chung, Sam Dawson and Justin Laguardia — became the North American champions at the National Freescale Cup Autonomous Model Car Competition. The annual event, sponsored by Freescale Semiconductor, challenges students to design and build an autonomous model car that relies on optical sensors, a small computer and student-developed software, in order to navigate a complex racetrack. The UC Davis engineers — calling themselves “Team Dinky” — qualified for this national cup after defeating 17 other teams during the Western Regional competition, which took place April 18, 2015, as part of UC Davis’ Picnic Day activities. Team Dinky then became one of the three U.S. teams to compete at the North America Freescale Cup Championship, which took place May 2 at New York’s Rochester Institute of Technology. The Aggie engineers’ vehicle sped aggressively through the racetrack and secured a decisive victory. Team Dinky developed their car as part of ECE’s Autonomous Vehicle Senior Design project course, under the direction of instructor and development engineer Lance Halsted. The Freescale Cup, formerly known as the Smart Car Race, began in 2003 when Korea’s Hanyang University hosted 80 teams of students. Since that modest origin, the annual event has expanded throughout North America, Europe, China, India, Malaysia and Latin America, impacting more than 15,000 students at more than 500 schools. The global competition requires student teams to build, program and race a model car around a track for speed, with victory going to the fastest car that completes the course without derailing.

with dual appointments in the UC Davis Departments of Computer Science, and Mechanical and Aerospace Engineering, has been honored with a cover story Raissa M. D’Souza in the July 2015 issue of Nature Physics. The report, “Anomalous Critical and Supercritical Phenomena in Explosive Percolation,” is coauthored by Jan Nagler, a professor in the Department of Nonlinear Dynamics & Network Dynamics Group, at Germany’s Max Planck Institute for Dynamics and Self-Organization. The study focuses on a mathematical concept known as the “percolation transition,” which refers to large-scale connectivity on an underlying network or lattice. Because of the impact on such a system’s macroscopic behavior, it is desirable to control the location of the percolation transition, in order to either enhance or delay its onset, and, more generally, to better understand the consequences of such control interventions. D’Souza and Nagler have focused on “explosive percolation” — the sudden emergence of large-scale connectivity that results from repeated small interventions designed to delay the percolation transition — which could become an emerging paradigm for modeling real-world systems ranging from social networks to nanotubes. D’Souza joined UC Davis as an assistant professor in 2005, rising to full professor in July 2014. She is a member of the UC Davis Complexity Sciences Center, and since 2007 also has served as an external professor at the Santa Fe Institute. Her research focuses on mathematical models of self-organization, phase transitions and the structure and function of networked systems.

MAE GRAD STUDENTS SHARE RESEARCH AWARD JOSEPH BARTHEL AND BO FU, both graduate students

in the UC Davis Department of Mechanical and Aerospace Engineering, are sharing this year’s N&M Sarigul-Klijn Space Engineering/Flight Research Award. The two aerospace researchers will split the $1,500 award. Barthel was honored for his proposal, “Optimization of Passive Radiation Shielding Onboard a Space Habitat Equipped with an Active Magnetic Solenoid.” His research focuses on protecting astronauts from harmful radiation, via “passive shielding” generated by magnetic fields: an approach that would greatly reduce the overall Bo Fu spacecraft mass required to keep its human inhabitants safe. Fu was acknowledged for his proposal, “Mechanics of Bounded Inextensible Membranes Subjected to External Forces,” which derives

from his research into solar sails. Building on his development of an attitude control technique for large solar sails, Fu now seeks in-depth understanding of how the shape of sail membrane structures can be manipulated in order to optimize control of such crafts, thereby optimizing their potential to serve as a cost-effective method of space cargo transportation. The N&M Sarigul-Klijn Space Engineering/Flight Research Award was established in 2003 by Nesrin Sarigul-Klijn, a professor in the UC Davis Department of Mechanical and Aerospace Engineering. That initial award commemorated the 100th anniversary of powered flight, and was designed to encourage graduate students to conduct research in flightrelated areas. The award is presented biannually, in odd-numbered years, by a subcommittee of the Space Engineering Research and Graduate Program (SpaceED), which Sarigul-Klijn directs.

CEE GRAD STUDENTS TAKE FIRST PLACE IN ANNUAL

BIG IDEAS@BERKELEY COMPETITION UC DAVIS CIVIL & ENVIRONMENTAL ENGINEERING (CEE) GRADUATE STUDENTS Kyle Fuller and Ezequiel Santillan,

along with colleagues Solange Astorga and Lisa Marroquin, shared two first-place victories in this year’s Big Ideas@ Berkeley competition. Their proposal, “Clean Water for Crops: As Simple as Sand and Seeds,” took top honors in the Global Health category, and was selected for the Grand Prize Pitch Day, where it also won first place in the Global Impact category. The combined awards include a $13,000 cash prize, which will be used to implement a pilot-scale system in the region targeted by the proposal. Fuller, Santillan and their team have focused on Sololá, Guatemala, one of many communities surrounding Lake Atitlán. Population growth during the past two decades has led to increased sewage discharge into the lake, whose waters have long been used to irrigate local crops. Wastewater treatment plants mitigate some contamination issues, but the plants lack a disinfection process, which poses a health risk to those consuming these foodstuffs. The winning Big Ideas proposal will employ slow-sand filtration, a tertiary treatment process already widely used to treat drinking water. Pathogen reduction will be enhanced further by including a filtration step through the seeds of the Moringa oleifera, a tree common to Guatemala and many other parts of Latin America. The seeds have anti-microbial properties that increase pathogen reduction by a factor of 10,000. Such low-cost, gravity-fed technology can be used to treat wastewater to a level satisfactory for crop irrigation in small, developing communities, particularly those that lack a reliable supply of fresh water.

She’s lead author of the first article, “Life Cycle-based Assessment of Energy Use and Greenhouse Gas Emissions in Almond Production, Part I: Analytical Framework and Baseline Results.” Her collaborators are Elias Marvinney, a graduate student in the UC Davis Department of Plant Sciences; Sonja Brodt, in the UC Davis Agricultural Sustainability Institute; and Weiyuan Zhu, a UC Davis graduate student in horticulture and agronomy. Marvinney is lead author of the second article, in collaboration with Kendall and Brodt: “Life Cycle-based Assessment of Energy Use and Greenhouse Gas Emissions in Almond Production, Part II: Uncertainty Analysis through Sensitivity Analysis and Scenario Testing.” California-grown almonds dominate the global market and provide more than 80 percent of the world’s commercial almonds. Both journal articles examine the environmental impact of this agricultural industry. Kendall and her colleagues noted that certain practices substantially reduce greenhouse gas emissions and energy use, including the strategic utilization of co-products, and the choice of water source and irrigation technology. Kendall joined UC Davis in 2007. Her research interests focus on lifecycle modeling as applied to transportation systems, energy systems, industrial ecology, construction materials and buildings, with the goal of developing sustainable systems.

NIELS GRØNBECH-JENSEN APPOINTED AS COSMOS EXECUTIVE DIRECTOR NIELS GRØNBECHJENSEN, a professor with

dual appointments in the UC Davis Department of Chemical Engineering and Materials Science, and the Department of Mathematics, has been named the Statewide Faculty Executive Niels Grønbech-Jensen Director of the California State Summer School for Mathematics and Science (COSMOS). Grønbech-Jensen has been filling this role in an interim capacity since late 2014, when COSMOS’ statewide administrative home was moved from the UC Office of the President to UC Davis. He also has been an active instructional participant, having taught in the UC Davis COSMOS program since 2004. “The founders of COSMOS created a unique interface between high school excellence in STEM and university education,” GrønbechJensen said, “and I’m dedicated to continue building on their vision. I’m excited to combine my instruction of the outstanding COSMOS students on my campus, with the efforts to sustain and grow the statewide program by coordinating administration and advocacy.” State legislation in 1998 established COSMOS in order to engage talented and motivated high school students in an intensive program of study, experimentation and activities, to further their interests and skills in STEM fields (science, technology, engineering and mathematics). The University of California has administered the program since it began. Sessions initially took place at UC Irvine and UC Santa Cruz; increasing demand prompted an expansion to UC Davis in 2001, and UC San Diego in ’04. Grønbech-Jensen’s research interests focus on computational materials and soft condensed matter, molecular dynamics, radiation damage, nonlinear dynamics and complex systems, numerical analysis and methods, macroscopic quantum phenomena, and superconducting device physics.

NSF GRANT AWARDED TO MAE PROFESSORS The National Science Foundation’s Division of Undergraduate Education has awarded a two-year grant of $249,965.00 to BARBARA LINKE and MOHAMED HAFEZ , professors in the UC Davis Department of Mechanical and Aerospace Engineering; and Lee Martin, an assistant professor in the UC Davis School of Education. Linke is the PI on their project, titled An Integrated STEM Approach for Studying Aerospace Engineering Design and Manufacturing. Linke, Hafez and Martin will develop a course to help undergraduate mechanical and aerospace engineering Barbara Linke students understand how airplanes fly, by taking the students through the process of designing, modeling, manufacturing and testing a prototype wing. This combination of design, manufacturing and experimental validation will show students how to integrate key topics such as the physics of flight, manufacturing processes and sustainability. Such an active, projectbased approach has been demonstrated by research to foster the development of deep, conceptual learning and, in turn, greater problem-solving flexibility in engineering. Mohamed Hafez Linke joined UC Davis in 2012. Her research focuses on manufacturing technologies; sustainable and energy-efficient manufacturing processes; home-scale 3D printing; surface engineering for aesthetic metal parts; food-processing equipment, automotive and aerospace parts, biomedical components and more. Hafez came to UC Davis in 1986, to teach theoretical aerodynamics, aeronautical engineering and computational fluid dynamics. His many awards include the 1998 UC Davis Prize for Undergraduate Teaching and Scholarly Achievement, and he’s a Fellow of the American Institute of Aeronautics and Astronautics. His research focuses on transonic aerodynamics and computational fluid dynamics.

NESRIN SARIGUL-KLIJN NAMED AN ASME FELLOW The American Society of Mechanical Engineers (ASME) has named NESRIN SARIGUL-KLIJN a Fellow. She and the entire 2015 class of ASME Fellows were honored at the society’s annual recognition reception. A professor in the Department of Mechanical and Aerospace Engineering, Sarigul-Klijn was recognized for “significant research contributions in the fields of mechanical, biomedical and aerospace engineering, especially in the areas of fluid-structure interactions, acoustics and noise control, vibrations, space vehicle trajectory optimization, flight testing of scaled aerospace vehicles, human spine discography, vehicle health monitoring and the dynamic separation of airlaunched, rocket-powered space vehicles.” Sarigul-Klijn completed her doctorate in 1984 at the University of Arizona, and then spent five years as a professor of aeronautical and astronautical engineering at Ohio State University. She was awarded two NASA Faculty Fellowships during her tenure at Ohio State, and in 1989 she joined the UC Davis College of Engineering.

UC DAVIS ENGINEERING UNDERGRAD WINS LAKE TAHOE APP CONTEST THE UC DAVIS TAHOE ENVIRONMENTAL RESEARCH CENTER (TERC) has launched a new smartphone app,

“Citizen Science Tahoe,” that encourages visitors of all ages to tap in what they see at Lake Tahoe; creating crowdsourced observational data that will be shared with the scientists to better understand conditions around the lake. The app, available for download at CitizenScienceTahoe. org, was programmed by Shahzeb Khan, a UC Davis sophomore studying computer science who won a university-wide competition for the best app proposal. “Working on the app and solving problems has been a fun challenge,” said Khan. “Collaborating with TERC has also been a great work experience.” The Citizen Science Tahoe app, which launched in midAugust 2015, turns Tahoe shoreline visitors into research partners, by encouraging them to share observational data about what they see, while walking along the celebrated lake’s beaches. This perceptual data will help lake researchers better understand Tahoe’s fragile nearshore: the lake region most frequently experienced, but — surprisingly — least investigated. Funding assistance for this project comes from the North Lake Tahoe Resort Association, along with a $150,000 grant from the Institute of Museum and Library Services.

BME PROFESSOR SHARED INNOVATIVE TEACHING METHODOLOGY AT ANNUAL NAE SYMPOSIUM EDUARDO A. SILVA , an assistant professor in the UC Davis

Department of Biomedical Engineering, attended the National Academy of Engineering’s annual Frontiers of Engineering Education Symposium, which took place Oct. 25-28, 2015, at the National Academies’ Beckman Center in Irvine, Calif. All invited participants were asked to outline their innovative teaching methods on posters displayed within an expo-style environment, where attendees circulated and listened to informal presentations from each speaker. Participants also met during smaller thematic sessions and panels, in order to collaborate and discuss different educational tools and strategies. Silva shared the “peer review” methodology that he has employed in his interdisciplinary UC Davis course, Physiology for Biomedical Engineers. This approach shares the responsibility of both teaching and learning with all students, which results in a highly engaged class from an early stage. Students identify and learn from the strengths and weaknesses of their peers, and are taught to provide concise,

constructive criticism while developing writing and analytical skills. Finally, the methodology itself teaches the essential skill of deconstructing a written idea/report into achievable and measurable tasks, which transforms the way students communicate with their peers and the surrounding society. Eduardo A. Silva Silva joined UC Davis in 2011. His research focuses on translation stem cell bioengineering, with the goal of developing new material platforms that will enable the control of stem/progenitor cell trafficking in the body. His lab explores chemical and biologically inspired design principles that will produce new material platforms to negotiate biological barriers such as the endothelial walls found in vascular networks.
