From sub-atomic to astronomical scales, we are working on the frontiers of science. A tradition of bridging boundaries has allowed us to probe fundamental questions at the intersections of different branches of science and mathematics and to create new fields of study. Because mathematics and the physical sciences are fundamental to many pursuits, including engineering, medicine and biology, we contribute to the education of most undergraduate students at UC San Diego.
Rommie Amaro, a professor of chemistry and biochemistry at UC San Diego, has won the 2016 Corwin Hansch Award, given by the Hansch-Fujita Foundation each year to a scholar under the age of 40 for significant contributions to the field of computer-aided drug design.
Amaro, who is the director of UC San Diego’s National Biomedical Computation Resource and a co-director of the Drug Design Data Resource, was presented with the award at the 2016 EuroQSAR meeting and the Gordon Research Conferences on Computer-Aided Drug Design in Verona, Italy.
The award, established in 2000, is named after the late honorary chair of the QSAR and Chemoinformatics Society and the pioneer of the interdisciplinary science of QSAR, Corwin Hansch.
Amaro received both her bachelor’s degree in chemical engineering and her PhD in chemistry at the University of Illinois at Urbana-Champaign. She was an assistant professor of pharmaceutical sciences, computer science and chemistry at UC Irvine for two years before being recruited to the faculty at UC San Diego in 2011.
Five physicists at the University of California San Diego have been named 2016 Fellows of the American Physical Society, a distinct honor of professional achievement from the nation’s largest society of physicists.
Richard Averitt, Jose Boedo, Brian Keating, Wouter-Jan Rappel and Massimo Vergassola were honored by the society this week for “exceptional contributions to the physics enterprise,” which can include “outstanding physics research, important applications of physics, leadership in or service to physics, or significant contributions to physics education.”
Surfers have a very intimate connection to the ocean. Their skin is bathed in the rushing tide, and crashing waves send salty seawater into their ears, eyes and throat. Inside and out, they are saturated with diverse molecules and bacteria to which the average person is not exposed. This prompts the question: How do these unique bacteria and chemicals impact human health? Cliff Kapono, UC San Diego chemistry doctoral student, is embarking on a worldwide quest to find out.
A native of the Big Island of Hawaii, Kapono is passionate about his heritage and promoting the well-being of people and our planet. As a scientist, he seeks to tap into the microscopic world of bacteria, fungi, viruses and other microbes. These microbiomes, or communities of microorganisms and their gene products, live in our bodies and on our skin and pervade much of the world around us. And scientists are just beginning to discover their impact on human and environmental health.

F. Duncan Haldane, the Princeton University physicist who was awarded 2016 Nobel Prize in Physics this week for his research into the properties of matter in extreme states, was a professor of physics at UC San Diego from 1986 to 1992.
Haldane, who joined the Princeton faculty after he left the La Jolla campus, shared the Nobel Prize with David Thouless of the University of Washington and J. Michael Kosterlitz of Brown University “for theoretical discoveries of topological phase transitions and topological phases of matter.”
“They have used advanced mathematical methods to study unusual phases, or states, of matter, such as superconductors, superfluids or thin magnetic films,” the Royal Swedish Academy of Sciences said in announcing the award.
Haldane said in an interview publicized by Princeton University on the day he was informed of his Nobel Prize that “My work was a kind of sleeper. It was a very theoretical thing. ... It didn't become such a big deal until my work got extended” by other scientists.
On the nature of discovery, he added, “All these things are things that no one expects. You stumble over something and then you find the big picture after.”
Elizabeth Villa, a biophysicist who is an assistant professor of chemistry and biochemistry, received a $2.325 million New Innovator Award from the National Institutes of Health.
She was one of only 48 researchers nationwide this year to receive the prestigious award, which was established in 2007 and is designed to support unusually innovative research from early career investigators who are within 10 years of their final degree or clinical residency and have not yet received a research project grant or equivalent NIH grant.
Villa, who will use her award for her research project on “Opening Windows into the Cell: Revealing the Molecular Architecture of the Nuclear Periphery,” received her Ph.D. in Biophysics from the University of Illinois at Urbana-Champaign working with Klaus Schulten on multiscale simulations of biomolecular complexes, where she worked closely with Joachim Frank developing computational tools for cryo-electron microscopy.
She was a Marie Curie postdoctoral fellow in the lab of Wolfgang Baumeister at the Max Planck Institute of Biochemistry in Munich. Her lab develops tools to observe macromolecular complexes in their natural environment, the cell. Her goal is to transform cryo-electron tomography into a high-resolution technique to unveil the structural dynamics of these complexes that is directly compatible with other biophysics experiments. She combines cell biology and cryo-electron microscopy to generate data, and use computational analysis and physical modeling to understand these data. Her current research is focused on studying the nuclear periphery, one of the most exciting and structurally uncharted territories in the cell.

This coupling between electrons and phonons determines how efficiently solar cells convert sunlight into electricity. It also plays key roles in superconductors that transfer electricity without losses, topological insulators that conduct electricity only on their surfaces, materials that drastically change their electrical resistance when exposed to a magnetic field, and more.
At the Department of Energy’s SLAC National Accelerator Laboratory, scientists can study these coupled motions in unprecedented detail with the world’s most powerful X-ray laser, the Linac Coherent Light Source (LCLS). LCLS is a DOE Office of Science User Facility.
Using a unique computational approach to rapidly sample, in millisecond time intervals, proteins in their natural state of gyrating, bobbing, and weaving, a research team from UC San Diego and Monash University in Australia has identified promising drug leads that may selectively combat heart disease, from arrhythmias to cardiac failure.
Reported in the September 5, 2016 Proceedings of the National Academy of Sciences (PNAS) Early Edition, the researchers used the computing power of Gordon andComet, based at the San Diego Supercomputer Center (SDSC) at UC San Diego; and Stampede, at the Texas Advanced Computing Center at the University of Texas at Austin, to perform an unprecedented survey of protein structures using accelerated molecular dynamics or aMD – a method that performs a more complete sampling of the myriad shapes and conformations that a target protein molecule may go through.
Biochemists at the University of California San Diego have uncovered patterns in the outer protein coat of group AStreptococcus that could finally lead to a vaccine against this highly infectious bacteria—responsible for more than 500,000 deaths a year, including toxic shock syndrome and necrotizing fasciitis or “flesh-eating disease.”
In a paper published in this week’s issue of Nature Microbiology, the researchers report that they had uncovered “hidden sequence patterns in the major surface protein and virulence factor” of group A Strep, called the M protein, that limit the body’s immune response against these bacteria.

Migratory birds often use warm, rising atmospheric currents to gain height with little energy expenditure when flying over long distances.
It’s a behavior known as thermal soaring that requires complex decision-making within the turbulent environment of a rising column of warm air from the sun baked surface of the earth. But exactly how birds navigate within this ever-changing environment to optimize their thermal soaring was unknown until a team of physicists and biologists at the University of California San Diego took an exacting computational look at the problem.
Biochemists at the University of California San Diego have developed artificial cell membranes that grow and remodel themselves in a manner similar to that of living mammalian cells.
The achievement, detailed in a paper published in this week’s issue of the Proceedings of the National Academy of Sciences, follows the successful design last year in the same laboratory of artificial, or synthetic, cell membranes capable of sustaining continual growth. The two developments now bring the researchers closer to mimicking all of the properties of living mammalian cell membranes with synthetic components.
Mathematics Professor James McKernan has been named by the Simons Foundation as a Simons Investigator, an honor that will provide him with an award of $100,000 per year in research support over the next five years.
In announcing his selection as a 2016 Simons Investigator, the foundation said that “McKernan, in collaboration with Caucher Birkar, Paolo Cascini, and Christopher D. Hacon, has established one of the cornerstones of the Minimal Model Program: the finite generation of canonical rings in all dimensions.”
McKernan, who received his doctorate in mathematics from Harvard University in 1991, was a professor at UC Santa Barbara and MIT before coming to UC San Diego and currently holds the Charles Lee Powell Endowed Chair in Mathematics.
His research is focused on birational geometry and his work has been recognized by professional organizations with numerous awards: the Clay Research Award in 2007 and the Cole Prize in Algebra in 2009. In 2011, he was elected to the Royal Society in the UK. He was also honored by being invited to and delivering a lecture at the International Congress of Mathematicians in Hyderabad in 2010.
A team of physicists that visualized the internal nanostructure of an intact butterfly wing has discovered two physical attributes that make those structures so bright and colorful.
“Over millions of years, butterflies have evolved sophisticated cellular mechanisms to grow brightly colored structures, normally for the purpose of camouflage as well as mating,” says Oleg Shpyrko, an associate professor of physics at UC San Diego, who headed the research effort. “It’s been known for a century that the wings of these beautiful creatures contain what are called photonic crystals, which can reflect light of only a particular color.”
Scientists at UC San Diego, MIT and Harvard University have engineered “topological plexcitons,” energy-carrying particles that could help make possible the design of new kinds of solar cells and miniaturized optical circuitry.
The researchers report their advance in an article published in the current issue of Nature Communications.
Within the Lilliputian world of solid state physics, light and matter interact in strange ways, exchanging energy back and forth between them.
“When light and matter interact, they exchange energy,” explained Joel Yuen-Zhou, an assistant professor of chemistry and biochemistry at UC San Diego and the first author of the paper. “Energy can flow back and forth between light in a metal (so called plasmon) and light in a molecule (so called exciton). When this exchange is much faster than their respective decay rates, their individual identities are lost, and it is more accurate to think about them as hybrid particles; excitons and plasmons marry to form plexcitons.”
