EAS Remembers Tsien Hsue-Shen
Qian Xuesen (also known as Tsien Hsue-Shen) (Aeronautics PhD '39), passed away on October 31, 2009. He was a student of Professor Theodore von Kármán and one of the founders of the Jet Propulsion Laboratory. "Dr. Tsien Hsue-Shen was one of the great scientist-engineers of the past century. He played an important role in the history of Caltech and the development of the Jet Propulsion Laboratory. We are also very proud of his many accomplishments in China." said President Chameau.

Regina Dugan Named Director of DARPA
Regina Dugan (PhD '93 Mechanical Engineering) has been named director of DARPA, the Defense Advanced Research Projects Agency of the Department of Defense. Dugan, the founder and CEO of RedXDefense, LLC, a Maryland-based firm that develops technologies to detect and counter explosives, becomes the 19th director and first woman to head DARPA, the DoD's principal research and development agency.
President Obama Presents Three EAS Faculty with the PECASE
In a special White House ceremony, President Obama will be presenting three EAS faculty: John Dabiri, Assistant Professor of Aeronautics and Bioengineering, Beverley McKeon, Assistant Professor of Aeronautics, and Joel Tropp, Assistant Professor of Applied and Computational Mathematics, with the Presidential Early Career Awards for Scientists and Engineers (PECASE). "These extraordinarily gifted young scientists and engineers represent the best in our country," President Obama said. Dabiri,describes the idea behind his PECASE-winning research as "giving underwater vehicles the enhanced performance of fish (e.g. efficiency, stealth, and maneuverablity) without mimicking the shape and swimming motions of fish. Instead, we replicate the vortex dynamics in the wakes of swimming fish." His "bio-inspired systems" were used by Lydia Ruiz (PhD '09 Mechanical Engineering), to demonstrateincreases in vehicle propulsive efficiency of over 50 percent.
McKeon is receiving the PECASE for her research on fundamental questions in complex turbulent boundary layers. McKeon states that "the ultimate goal is to incorporate recent advances in the understanding of flow physics in order to develop low order models of flow over surfaces for Air Force applications". Tropp's PECASE-winning research "focuses on developing new algorithms for solving inverse problems, a basic challenge that arises throughout the mathematical sciences. Inverse problems also appear in medical imaging, in communication systems, in statistical data analysis, and a host of other areas." He uses tools from modern applied mathematics, such as optimization techniques and randomized algorithms to collect partial information about an object of interest, and incorporate additional background knowledge to develop a complete picture of the object.
Other researchers receiving the PECASE award this year are Joshua K. Willis from the Jet Propulsion Laboratory and the following Caltech Alumni Elizabeth Boon, (PhD '03 CCE), Markus J. Buehler, (Post doc in CCE) Michael J. Hochberg, (Ph.D. '06 EAS - Applied Physics), Justin K. Romberg, (Post doc in EAS - Applied and Computational Mathematics), Cecilia R. Aragon, (B.S. '82 PMA), Jason Graetz, (Ph.D. '03 EAS - Materials Science), and Ioannis Chasiotis, (Ph.D. '02 EAS - Aerospace).
Four EAS Alumni Named by Caltech as Distinguished Alumni
Four EAS alumni have garnered the highest honor the Institute bestows and been named Caltech Distinguished Alumni: David B. Kirk (MS '90 Computer Science, PhD '93 Computer Science); Robert J. Lang, (BS '82 Electrical Engineering, PhD '86 Applied Physics); François M. Morel (MS '68 Civil Engineering, PhD '72 Engineering Science) and David W. Thompson (MS '78 Aeronautics). Kudos to all!
