2018 Caltech Distinguished Alumni


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] [Techer article]

Quantum and non-linear forces yield peculiar thermal expansion in silicon


Most materials expand when heated. At temperatures below room temperature, silicon shows the opposite behavior, shrinking as it is heated. Even at room temperature the normal thermal expansion of silicon is rather small. A team led by Professor Brent Fultz wanted to know why, and found that the unusual property is the result of quantum effects coupled by the nonlinear forces between atoms in silicon. [Read the paper]

No Motor, No Battery, No Problem


Chiara Daraio, Professor of Mechanical Engineering and Applied Physics, and colleagues have developed robots capable of self-propulsion without using any motors, servos, or power supply. Instead, these first-of-their-kind devices paddle through water as the material they are constructed from deforms with temperature changes. "Combining simple motions together, we were able to embed programming into the material to carry out a sequence of complex behaviors," says Caltech postdoctoral scholar Osama R. Bilal, who is co-first author of the PNAS paper is titled "Harnessing bistability for directional propulsion of soft, untethered robots." [Caltech story]

Professor Ravichandran To Give 2018 Robert Henry Thurston Lecture


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.

Ida Qin Receives 2018 Henry Ford II Scholar Award


Mechanical engineering student Yidan (Ida) Qin, advised by Professor Joel Burdick, is a recipient of the 2018 Henry Ford II Scholar Award. She is interested in robotics and machine learning and is developing innovative rehabilitation treatment plans for patients with spinal cord injury using machine learning techniques and the control of bipedal robots inspired by them. The Henry Ford II Scholar Award is funded under an endowment provided by the Ford Motor Company Fund. The award is made annually to engineering students with the best academic record in their discipline.

Solving Pieces of the Genetic Puzzle


Postdoctoral scholar Nathan Belliveau working in the laboratory of Professor Rob Phillips has applied a method called Sort-Seq to mutate small pieces of noncoding regions in E. coli and determined which regions contain binding sites. Binding sites are the locations where specialized proteins that are involved in transcription—the first step in the process of gene expression—attach to DNA. "Humans have such a wide variety of cells—muscle cells, neurons, photoreceptors, blood cells, to name a few," says Professor Phillips. "They all have the same DNA, so how do they each turn out so differently? The answer lies in the fact that genes can be regulated—turned on or off, dialed up and dialed down—differently in different tissues. Until now, there have been no general principles to help us understand how this regulation was encoded." [Caltech story]

Butterfly Wings Inspire Light-Manipulating Surface for Medical Implants



Professor Hyuck Choo along with postdoctoral researchers Radwanul Hasan Siddique, and graduate student Vinayak Narasimhan working in the Choo lab have developed a synthetic analogue for eye implants that makes them more effective and longer-lasting. The work was inspired by tiny nanostructures on transparent butterfly wings. The eye implant is shaped like a tiny drum, the width of a few strands of hair. When inserted into an eye, its surface flexes with increasing eye pressure, narrowing the depth of the cavity inside the drum. That depth can be measured by a handheld reader, giving a direct measurement of how much pressure the implant is under. [Caltech story]

Graduate Student Wins AAAS Mass Media Fellowship


Giuliana Viglione, a graduate student in Professor Andrew Thompson’s group and a member of the first E111 class has been selected to join the 2018 American Association for the Advancement of Science (AAAS) Mass Media Science & Engineering Fellows Program. The fellows are placed at media organizations nationwide and trained to sharpening their abilities to communicate complex scientific issues to the public. In her research, Giuliana uses robots to investigate small-scale motions in the ocean and what their effect on climate may be.  She will be spending the summer working at King5, an NBC affiliate in Seattle, where she will use her expertise to report on the effects of climate change in the Pacific Northwest.

Exploring Caltech’s Dynamic History of Teaching and Learning


A new exhibit on the third floor of the Center for Student Services highlights teaching and learning at Caltech through six frames: Laboratory Learning, Field-based Learning, Informal Learning, Thinking at the Board, Classes and Demonstrations, and Acts of Writing. It encourages the viewer to travel from the austere classrooms of the early days of Throop University to the diverse scenes of Caltech today, and to explore the interrelationships as they echo across eras.
