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.

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]

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.

Joel (J.N.) Franklin Passes Away

11-28-17

Joel (J.N.) Franklin, Professor of Applied Mathematics, Emeritus, passed away on November 18, 2017 at the age of 87. Professor Franklin joined Caltech in 1957 and worked closely with Gilbert McCann, professor of applied science, who was one of the early champions of computing at Caltech (and inventor of an analog computer in 1946). Professor Dan Meiron recalls, "Joel excelled as a scholar and researcher … if any of us in applied math—and the Institute in general—had any questions about matrix theory, linear programming, etc. we could consult with Joel and he always pointed us to the relevant results often connected to work he had done in the past."

Professor Rosakis Named AAAS Fellow

11-20-17

Ares J. Rosakis, Theodore von Karman Professor of Aeronautics and Mechanical Engineering, has been named fellows of the American Association for the Advancement of Science (AAAS). This year's 396 AAAS fellows have been recognized for their "scientifically or socially distinguished efforts to advance science or its applications," according to the AAAS. Professor Rosakis was specifically recognized for his “distinguished contributions in the field of aeronautics and mechanical engineering, particularly for fracture mechanics of materials ranging from thin films to earthquakes.” [Caltech story]

Engineers Create Stable Plasma Ring in Open Air

11-13-17

For the first time, Professor Morteza Gharib and colleagues have created a stable ring of plasma in open air using just a stream of water and a crystal plate. The team fired the water jet at surfaces of different textures and found that the smoother the surface, the clearer the structure of the plasma ring. The ring is stable, and as long as the water continues to flow, the ring maintains its shape and size. [Caltech story]
