Professor Tropp Receives Pioneer Award
Joel A. Tropp, Professor of Applied and Computational Mathematics, will receive the Compressive Sampling Pioneer Award at this year’s International Society for Optics and Photonics - Defense Security and Sensing conference (SPIE. DSS). He is one of the first researchers to contribute to the field of sparse approximation, which is also known as compressive sampling. At the conference he will give a presentation on sampling theorems for structured signals, based on his paper entitled “Living on the Edge.”
The Thomson Reuters compilation of the most highly cited researchers— those in the top 1%—from the period 2002–2012 include EAS professors Harry Atwater, Richard Murray, Joel Tropp, John Seinfeld, Kerry Vahala, and Paul Wennberg. Other Caltech professors were also among the top 1%—including Colin Camerer, Mark Davis, Richard Ellis, William Goddard, Robert Grubbs, Hiroo Kanamori, Jeff Kimble, John O’Doherty, and Charles Steidel. This compilation aims to identify researchers with exceptional impact on their respective fields. [Detailed information on the methodology]
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).
