2018 Caltech Distinguished Alumni

05-24-18

Caltech has recognized three Engineering and Applied Science (EAS) graduates with the Distinguished Alumni Award, the highest honor regularly bestowed by the Institute. Gary Demos (BS '71, Engineering and Applied Science), Gary A. Flandro (MS '60, PhD '67, Aeronautics), and Ronald H. Willens (BS '53 Physics, MS '54 Mechanical Engineering, PhD '61 Engineering Science). Demos was recognized “for his pioneering achievement in the development of computer-generated images (CGI) for use in motion pictures, and in digital film scanning and recording.” Flandro was recognized for “his seminal contributions to the design and engineering of multi-outer-planet missions, including the Grand Tour, the course set for the epic explorations of the Voyager spacecraft.” Willens was honored for “his innovative and revolutionary contributions to advanced internet connectivity and telecommunications. He pioneered the Remote Authentication Dial-in User Service (RADIUS) as an access server authentication and accounting protocol, which was adapted by the Internet Engineering Task Force (IETF) standards.” [Caltech story]

Professor Ravichandran To Give 2018 Robert Henry Thurston Lecture

05-15-18

Guruswami (Ravi) Ravichandran, John E. Goode, Jr., Professor of Aerospace and Mechanical Engineering; Otis Booth Leadership Chair, Division of Engineering and Applied Science, has been selected to give the 2018 American Society of Mechanical Engineers (ASME) Robert Henry Thurston Lecture at ASME Mechanical Engineering Congress & Exposition in November. He has been awarded this lectureship "for pioneering contributions to mechanics of materials, particularly dynamic deformation, damage and failure, micro/nano mechanics, wave propagation, composites, active materials, cell mechanics and experimental methods.” The lecture was established by the first ASME president to provide an opportunity for leaders in engineering to give a thought provoking lecture on a subject of broad interest to engineers.

09-11-17

G. Ravichandran, John E. Goode, Jr., Professor of Aerospace and Mechanical Engineering; Otis Booth Leadership Chair, Division of Engineering and Applied Science, has been elected to the Academy of Europe (Academia Europaea). The Academia Europaea was founded in 1988 and is an organization of eminent, individual scholars from across the continent of Europe. The 3000 members cover a wide range of academic disciplines including the humanities, social, physical and life sciences as well as mathematics, engineering and medicine. In addition to Professor Ravichandran, EAS Past Chair Ares Rosakis, Caltech's Provost Edward Stolper, the Institute's Past President David Baltimore, and Professor Alexander Varshavsky are members of the Academy.

How Friction Evolves During an Earthquake

08-15-17

Professor Ares Rosakis, and colleagues including Professor Nadia Lapusta and Research Scientist Vito Rubino, are studying the way friction changes along a fault during a seismic event by simulating quakes in a lab. "Our unique facility … allows us for the first time to study friction point-wise and without having to assume that sliding occurs uniformly, as is done in classical friction studies," Rosakis explains. Professor Lapusta adds, “some numerical models of earthquake rupture … have used friction laws with slip-velocity dependence… It is gratifying to see those formulations validated by the spontaneous mini-earthquake ruptures in our study.

Earthquakes Can Make Thrust Faults Open Violently and Snap Shut

05-01-17

Ares J. Rosakis, Theodore von Karman Professor of Aeronautics and Mechanical Engineering, and colleagues at Caltech and École normale supérieure in Paris have discovered that fast ruptures propagating up toward the earth's surface along a thrust fault can cause one side of a fault to twist away from the other, opening up a gap of up to a few meters that then snaps shut.

The Future is Autonomous

05-01-17

On April 19, 2017 Electrical Engineering alumnus Evangelos Simoudis (BS '83) moderated a panel titled "The Road Ahead: A Panel on the Future of Driverless Vehicles," hosted by the Caltech Associates. The panel members were Professors Mory Gharib, Richard Murray, and Pietro Perona, along with Reuters automotive industry reporter, Paul Lienert. They discuss a variety of opportunities and challenges associated with autonomous technologies and systems. Beyond the legal and ethical challenges, several technological obstacles must be overcome before driverless cars become common on the road. One key challenge is teaching driverless cars how to read the behavior of other cars and react accordingly. Professor Perona described the problem of a car attempting to merge onto a crowded freeway. A driverless car would see an impenetrable wall of vehicles, but a human driver could edge forward and wave at other drivers to work his or her way into the line of traffic. [Caltech story]
