Ares J. Rosakis, Theodore von Karman Professor of Aeronautics and Mechanical Engineering, is the 2015 recipient of the Sia Nemat-Nasser Medal “for innovative singular theoretical and experimental contributions in dynamic fracture and optical techniques, and their application to rupture faults.” The Sia Nemat-Nasser Medal is awarded by the Society for Experimental Mechanics (SEM) and recognizes an individual for distinguished, innovative, and outstanding work that has realized the impact of experimental mechanics on other scientific and engineering fields through an integrated multidisciplinary research. Professor Rosakis received the award at the 2015 SEM annual conference. At the same event Professor Chiara Daraio and colleagues received the 2015 M. Hetényi Award for best research paper published in Experimental Mechanics. Furthermore, EAS alumnus Hugh Bruck became a 2015 fellow and EAS alumnus John Lambros received the M.M. Frocht Award.

Professor Daraio Wins Presidential Early Career Award

07-24-12

Chiara Daraio, Professor of Aeronautics and Applied Physics, has won a 2012 Presidential Early Career Award for Scientists and Engineers (PECASE). Daraio was recognized for her "pioneering contributions to nonlinear mechanical phenomena in acoustic crystals, granular material, and multifunctional nanostructures, and for mentoring women and providing research opportunities for high school and undergraduate students."

"The entire Caltech community is proud to see Professor Daraio recognized with this presidential honor, not only for her pioneering research accomplishments, but also for her commitment to students and diversity," says Chair Ares Rosakis. "Even though she is near the beginning of her career she already embodies the key attributes of the Division of Engineering and Applied Science at Caltech." [Caltech Release]

Winners of the 2012 Demetriades - Tsafka - Kokkalis Prizes Announced

06-14-12

The student winners of the 2012 Demetriades - Tsafka - Kokkalis Prizes were announced at a special luncheon with the Demetriades - Tsafka – Kokkalis family. Philip Romero received the prize in Biotechnology for his work on developing statistical models of proteins with Frances Arnold. Michael Mello was the recipient of the prize in Seismo-Engineering, Prediction, and Protection for his work with Ares Rosakis on developing a novel methodology for identifying the unique ground motion signatures of supershear earthquakes. Leslie O’Leary received the prize in Environmentally Benign Renewable Energy Sources for her pathbreaking work on the properties of semiconductor interfaces with Nate Lewis and Bob Grubbs. This year there were two winners for the prize in Nanotechnology. One winner was Andrew Jennings for his experimental and modeling work in nanomechanics with Julia Greer. The other winner of the Nanotechnology prize was Jordan Raney who has worked with Chiara Daraio to develop new chemical synthesis methods to control the properties of carbon nanotubes.

How an Idea Becomes a Business

03-29-11

Students in Ken Pickar's course Entrepreneurial Development (E 102) have the opportunity to identify a technology currently under study at Caltech and develop a business plan for it. The ideas used by the students this year included a solid-state memory technology developed by Jehoshua (Shuki) Bruck, Gordon and Betty Moore Professor of Computation and Neural Systems and Electrical Engineering. In this business plan the students proposed targeting Netflix and other high-volume streaming content providers. Another team pinpointed a new market for the vertical wind turbines of John O. Dabiri, Professor of Aeronautics and Bioengineering. A third team pitched a noninvasive method for breaking up arterial plaques using the concentrated-acoustic-pulse technology developed by Chiara Daraio, Professor of Aeronautics and Applied Physics.

Caltech Researchers Create "Sound Bullets"

04-22-10

Alessandro Spadoni, Postdoctoral Scholar, and Chiara Daraio, Assistant Professor of Aeronautics and Applied Physics, have built a nonlinear acoustic lens that produces highly focused, high-amplitude acoustic signals dubbed "sound bullets." The combination of the acoustic lens and sound bullets have "the potential to revolutionize applications from medical imaging and therapy to the nondestructive evaluation of materials and engineering systems," says Professor Daraio.
