Richard M. Murray, Thomas E. and Doris Everhart Professor of Control and Dynamical Systems and Bioengineering, has been named to the Defense Innovation Advisory Board by Secretary of Defense Ash Carter. Professor Murray joins 14 other scholars and innovators who will focus on new technologies and organizational behavior and culture. Secretary Carter has asked them to identify technology and practices from the private sector that could be used by the Department of Defense (DOD). [Caltech story]
On July 15, 2016, Kaushik Bhattacharya, Howell N. Tyson, Sr., Professor of Mechanics and Materials Science, will take over from Professor Morteza Gharib as Caltech vice provost. His research group studies the mechanical behavior of solids and uses theory to guide the development of new materials. He has made contributions on a wide array of topics, ranging from the fundamental mechanics of materials, to active materials and devices, to multi-scale and multi-physics scale simulation of materials. Though trained as a theoretician, he is well known for live demonstrations of shape-memory materials in action. "Kaushik's technical strength, deep knowledge of the Institute, energy, and enthusiasm will serve him and us well as he takes on this important role," said EAS Division Chair G. (Ravi) Ravichandran.

Richard M. Murray, Thomas E. and Doris Everhart Professor of Control and Dynamical Systems and Bioengineering, is the recipient of the 2017 IEEE Control Systems Award, for outstanding contributions to control systems engineering, science, or technology. Professor Murray is receiving the award, “for contributions to the theory and applications of nonlinear and networked control systems." [List of award recipients]
The Community Seismic Network’s (CSN) tight network of low-cost detectors are improving the resolution of seismic data gathering and could offer city inspectors crucial information on building damage after a quake. On February 18, 2015, an explosion rattled the ExxonMobil refinery in Torrance, causing ground shaking equivalent to that of a magnitude-2.0 earthquake and blasting out an air pressure wave similar to a sonic boom. Traveling at 343 meters per second the air pressure wave reached a 52-story high-rise in downtown Los Angeles 66 seconds after the blast. The building's seismometers, which are part of the CSN, noted and recorded the motion of each individual floor. "We want first responders, structural engineers, and facilities engineers to be able to make decisions based on what the data say," explained Monica Kohler, Research Assistant Professor of Mechanical and Civil Engineering, and the lead author of a paper detailing the high-rise's response that recently appeared in the journal Earthquake Spectra.

Nadia Lapusta, Professor of Mechanical Engineering and Geophysics, and Caltech alumnus Dr. Junle Jiang, have linked the patterns of microseismicity to the depth extension of large earthquakes, both through modeling and observationally. They argue that fault segments which do not have concentrated microseismicity at the bottom of the seismogenic zone must have had deeper, larger earthquakes than currently believed. A number of segments on the San Andreas fault appear to fall into that category. The potential for such deeper earthquakes in the future would imply higher seismic hazard.

The student winners of the 2016 Demetriades - Tsafka - Kokkalis Prizes were announced at a special dinner with the Demetriades - Tsafka – Kokkalis family. Rachel P. Galimidi received the prize in Biotechnology for her work with Professor Pamela Bjorkman aimed to further understand the mechanism of HIV evasion of the humoral immune response. Junle Jiang was the recipient of the prize in Seismo-Engineering, Prediction, and Protection for his work with Nadia Lapusta which used probabilistic inversion tools to understand the deep-ocean trench generated tsunamis that occurred during the subduction-zone earthquakes in Japan and Chile. Yinglu Tang working with Dr. Jeff Snyder received the prize in Environmentally Benign Renewable Energy Sources for her work on thermoelectric skutterudites for mid-temperature applications such as automotive waste heat recovery. The second winner in this category was Changhong Zhao who worked with Professor Steven Low to study the control and optimization of modern electric power systems. The winner of the prize in Nanotechnology was Gustavo Rios whose research involves development of a modular, scalable, nanofabricated neural probe system for dense 3-D electrophysiology to study animal brains. Rio’s graduate advisor was Professor Thanos Siapas. The prize in Entrepreneurship was given to Anton A. Toutov who was advised by Professor Robert Grubbs. His research interests lie in using fundamental chemistry to development radically new, sustainable ways to make everyday chemical products and generate clean energy.

Jomela Meng, a graduate student working with Professor Tim Colonius, is a recipient of the 2016 Richard B. Chapman Memorial Award. Her research leveraged direct numerical simulations to investigate the fundamental flow physics associated with single droplet aerobreakup. The Richard B. Chapman Memorial Award is given to an EAS graduate student in hydrodynamics who has distinguished himself or herself in research.
Simon Lapointe, a graduate student working with Professor Guillaume Blanquart, is a recipient of the 2016 Richard B. Chapman Memorial Award. As part of his doctoral research, he performed numerical simulations to study premixed hydrocarbon flames at high turbulence intensities. The Richard B. Chapman Memorial Award is given to an EAS graduate student in hydrodynamics who has distinguished himself or herself in research.
Mechanical Engineering student Tyler Okamoto, mentored by Professor Sergio Pellegrino, is a recipient of the 2016 Henry Ford II Scholar Award. He is working with Professor Pellegrino’s team to build an autonomous reconfigurable space telescope using multiple nanosatellites that align in space to create a camera and mirror assembly. The Henry Ford II Scholar Award is funded under an endowment provided by the Ford Motor Company Fund. The award is made annually to engineering students with the best academic record at the end of the third year of undergraduate study.
