President Rosenbaum Highlights Postdocs as "Unsung Heroes"

09-24-18

In a letter to the Caltech community during National Postdoc Appreciation Week, the Caltech President emphasizes the role this key group plays at the Institute. He stated, “Caltech's mission of world-leading research and education depends crucially on our postdoctoral scholars. Although their time at Caltech may be short, they quickly become vital parts of the Institute's intellectual fabric.” [President’s Letter] [EAS Postdoc Resource Page]

Student-Built Satellite Telescope Prepares for Space

08-16-18

After nearly a decade of work, a modular reconfigurable space telescope designed by students in the Ae 105 Aerospace Engineering class is nearly ready to launch. That telescope, which came to be known as AAReST (Autonomous Assembly of a Reconfigurable Space Telescope), was designed and built in large part by the students in the class, working in collaboration with the Surrey Space Centre in England and the Indian Institute of Space Science and Technology. Professor Pellegrino says that the students working on AAReST have learned how to collaborate across continents and gained skills that will continue to serve them for years to come. In addition, he says, he's proud to have given several generations of aerospace students the opportunity to work on a real space mission. When the mission launches in 2019, dozens of past and present Caltech students—along with their collaborators nearby and abroad—will be watching and holding their breath to see whether their hard work pays off.

Engineers Taught a Drone to Herd Birds Away From Airports

08-08-18

Soon-Jo Chung, Associate Professor of Aerospace and Bren Scholar; Jet Propulsion Laboratory Research Scientist, and colleagues have developed a new control algorithm that enables a single drone to herd an entire flock of birds away from the airspace of an airport. The effectiveness of the algorithm is only limited by the number and size of the incoming birds, Professor Chung says, adding that the team plans to explore ways to scale the project up for multiple drones dealing with multiple flocks.[Caltech story]

Graduate Student Places 4th in National Soaring Competition

07-31-18

GALCIT Graduate student Michael Marshall, who is a member of Professor Sergio Pellegrino’s Space Structures Laboratory, has received the Rudolph W. Mozer Trophy from the Soaring Society of America (SSA) for being the highest ranking contestant under 26 years of age at any U.S. National Soaring contest. He also placed 4th in the U.S. National Soaring contest. Soaring involves flying without flapping wings or using engine power, or as described by the SSA “to fly as the hawk and eagle has been mankind's dream for centuries. Modern sailplanes make soaring flight possible, and with them humans can fly higher, faster, and farther than the greatest of birds, using only an invisible force of nature to stay aloft.” [SSA news]

Dragonfly Larvae Inspire New Designs for Prosthetic Heart Valves

07-17-18

Professor Mory Gharib and postdoctoral researcher Chris Roh (MS '13, PhD '17) have studied the design and control of the jets that dragonfly larvae use to propel themselves to re-design health values. "The current heart valve design is a one-size-fits-all, where no patient-specific design is considered, and this causes many post-transplant complications," Dr. Roh says. "We believe that an intentionally off-centered opening of the heart valve to more closely match the patient's original blood flow will be an important design parameter that can be adjusted based on each patient's heart morphology."

Richard B. Chapman Memorial Awards

07-03-18

Morgane Anne Marie Grivel advised by Professor Morteza Gharib, Kazuki Maeda advised Professor Tim Colonius, and Jason Schlup advised by Professor Guillaume Blanquart are recipients of the 2018 Richard B. Chapman Memorial Award. Morgane's research focuses on using hydrophilic and hydrophobic regions to modify hydrodynamic flows. Jason's research utilized computational fluid dynamics to investigate the highly unstable combustion of hydrogen-air mixtures with a focus on accurate, cost-effective modeling techniques. Kazuki does research in multi-phase flow, computational fluid dynamics, and biomedical engineering. The Richard B. Chapman Memorial Award is given to an EAS graduate student in hydrodynamics who has distinguished himself or herself in research.

A Gift of Autonomy

06-21-18

Trustees Lynn Booth and Kent Kresa have decided to endow the Booth-Kresa Leadership Chair for Center for Autonomous Systems and Technologies (CAST). Professor Mory Gharib explains, “in science and technology, freedom is the most powerful gift you can offer. The Booth-Kresa Leadership Chair will help ensure that CAST can move nimbly into our emerging more autonomous future, unleashing the creativity of our faculty, students, and scholars. I am personally grateful to Lynn and Kent for their generosity, enthusiasm, and trust in our vision.” [Breakthrough story]

Professor McKeon Receives Northrop Grumman Prize for Excellence in Teaching

06-12-18

Beverley J. McKeon, Theodore von Karman Professor of Aeronautics, is the recipient of the 2018 Northrop Grumman Prize for Excellence in Teaching. The Prize is awarded to an EAS professor who demonstrates, in the broadest sense, unusual ability, creativity, and innovation in undergraduate and graduate classroom or laboratory teaching. A nomination for Professor Mckeon read, “she is a firm believer in the importance of having all students, regardless of their ultimate specialty, participate in laboratory coursework. Her courses serve as a solid foundation for graduate level research across disciplines, both technically and with regards to skills relevant to doctoral and industrial research. She takes tough subjects and uses her colorful approach to make the concept easy to comprehend.” [Caltech story]

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]
