CAST Awards Seed Funding to Three New Projects
Caltech Center for Autonomous Systems and Technologies (CAST) has awarded seed funding to three new collaborative projects. The first project was proposed by Aerospace postdoctoral scholar H. Jane Bae, along with Professors McKeon, Tropp, and Meiron. It aims to develop algorithms to predict the onset of extreme events in real time thus allowing autonomous air vehicles to avoid or compensate for the rough turbulent airflow. The second project was proposed by Professors Effros, and Murray and will focus a new approach to the analysis, design, and implementation of complex, networked systems with the goal of optimizing latency in information sharing. The third project was proposed by Professor Thompson and JPL colleagues I. Fenty, R. Castano, D. Limonadi, and G. Woodward. This project plans to take a step towards developing autonomous observing arrays that will use ocean robotics to deploy ice melt-rate instruments within ice shelf cavities.

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).
John Dabiri and Joel Tropp Win ONR Young Investigator Awards
Two EAS faculty have won ONR Young Investigator Awards: John Dabiri, Assistant Professor of Aeronautics and Bioengineering, and Joel Tropp, Assistant Professor of Appliedand Computational Mathematics. The objectives of the Young Investigator Program are to attract to naval research outstanding new faculty members, to support their research, and to encourage their teaching and research careers. Tropp's award is for his research into "Compressive Signal Processing - Theory and Algorithms"; and Dabiri's award is for work in "Optimal Propulsion Methodologies for Hybrid Screw-based, Bio-inspired Systems". ONR announced 27 new awards for 2008.
