Establishing the Caltech Field Laboratory for Optimized Wind Energy (FLOWE)

05-17-10

John O. Dabiri, Associate Professor of Aeronautics and Bioengineering, has purchased two acres of land north of Los Angeles, where he is establishing the Caltech Field Laboratory for Optimized Wind Energy (FLOWE). The goal is "to extract significantly more wind energy from a given parcel of land than is currently possible... [by taking] advantage of constructive aerodynamic interference between closely spaced vertical-axis wind turbines." says Dabiri whose inspiration for this project came from observation of schooling fish.

John Dabiri and Kakani Katija Link Tiny Sea Creatures to Large-scale Ocean Mixing

07-29-09

John Dabiri, Assistant Professor of Aeronautics and Bioengineering, and graduate student Kakani Katija have discovered a new mechanism that explains how some of the ocean's tiniest swimming animals can have a huge impact on large-scale ocean mixing. Dabiri describes, "we've been studying swimming animals for quite some time, the perspective we usually take is that of how the ocean—by its currents, temperature, and chemistry—is affecting the animals. But there have been increasing suggestions that the inverse is also important—how the animals themselves, via swimming, might impact the ocean environment." Ares Rosakis, the Theodore von Kármán Professor of Aeronautics and Mechanical Engineering and chair of the EAS Division described the research as, "truly reflective of the type of exciting, without-boundaries research at which Caltech engineering professors excel."

President Obama Presents Three EAS Faculty with the PECASE

07-10-09

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 Named One of "Brilliant Ten" by Popular Science Magazine

10-15-08

John Dabiri, assistant professor of aeronautics and bioengineering, has been named one of "Brilliant Ten" by Popular Science Magazine. Dabiri is the youngest scientist on the list at just 28 years of age. Dubbed "the jellyfish engineer" by the magazine, he garnered the award for his studies of the intricacies of jellyfish locomotion. Using a custom-built, high-definition video camera and a water-particle-illuminating laser, Dabiri and his colleagues are able to examine the fluid dynamics that determine how jellyfish propel themselves through their watery environment. Their hope is that those insights will be used to improve the designs of nonbiological systems as diverse as military submarines and onshore windmills. [Popular Science Article]

John Dabiri and Joel Tropp Win ONR Young Investigator Awards

03-17-08

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.
