Abigail Jiang Wins SURF Speaking Competition

02-01-21

Materials science undergraduate student Abigail Jiang is the winner of the Doris S. Perpall Summer Undergraduate Research Fellowships (SURF) Speaking Competition. She was recognized as the best speaker out of 200 students who presented their SURF research. Abigail's SURF project was entitled, “Developing Physical Lab Infrastructure for Thin Film Material Growth and Evaluation." Robert C. Perpall, a Caltech mechanical engineering alumnus and past member of the SURF Board, created the Doris S. Perpall SURF speaking prize in 1993 as an incentive for Caltech students to give excellent oral presentations. [View Presentations]

Caltech and NTT Research Launch Collaboration to Develop World’s Fastest Coherent Ising Machine

01-25-21

Researchers from Caltech and NTT Research are collaborating to develop a high-speed Coherent Ising Machine (CIM). A CIM is a network of optical parametric oscillators (OPOs) programmed to solve problems that have been mapped to an Ising model, which is a mathematical abstraction of magnetic systems composed of competitively interacting spins, or angular momentums of fundamental particles. The principal investigator at Caltech for this four-and-a-half-year joint project is Kerry Vahala, Ted and Ginger Jenkins Professor of Information Science and Technology and Applied Physics; Executive Officer for Applied Physics and Materials Science. “We are delighted at the prospect of working with Professor Vahala to develop an extremely small and high-speed CIM,” said NTT Research PHI Lab Director, Yoshihisa Yamamoto. “This work will advance our understanding of the CIM’s capabilities, map well with ongoing and related work with other institutions, provide new demonstrations of this awesomely powerful new information system and, we hope, set standards for the CIM’s speed and size.” [NTT Research story] [Business Wire story]

Studying Chaos with One of the World's Fastest Cameras

01-14-21

There are things in life that can be predicted reasonably well. The tides rise and fall. A billiard ball bounces around a table according to orderly geometry. And then there are things that defy easy prediction: The hurricane that changes direction without warning. The splashing of water in a fountain. These phenomena and others like them can be described as chaotic systems. Lihong Wang, Bren Professor of Medical Engineering and Electrical Engineering, has developed a new tool that might help to better understand chaotic systems. [Caltech story]

Tiny Shape-Shifting Polymers Developed for Potential Medical Applications

01-04-21

Julia Greer, Ruben F. and Donna Mettler Professor of Materials Science, Mechanics and Medical Engineering; Fletcher Jones Foundation Director of the Kavli Nanoscience Institute, has developed a process for generating three-dimensional architected polymers with heat-dependent "shape memory" properties: that is, when heated, the material folds and unfolds itself into a new preordained shape. These shape memory polymers could one day be used to perform complex tasks inside the human body, such as unclogging a blocked artery or pulling out a blood clot. [Caltech story]

Waterman Awardee Dabiri Featured in National Science Foundation Video Profile

12-16-20

The National Science Foundation (NSF) honored John O. Dabiri, Centennial Professor of Aeronautics and Mechanical Engineering, with the 2020 Alan T. Waterman Award. The NSF has released a video interview with the Waterman awardees. The Alan T. Waterman Award is given to an outstanding young U.S. scientist or engineer along with a medal and other recognition. "This year's scientific pioneers are innovators who are creatively addressing some of the most challenging scientific questions," said NSF Director Sethuraman Panchanathan. "John Dabiri has looked to the fluid mechanics of sea life for inspiration to build better wind farms that appear to boost efficiency with a much smaller footprint."

EAS Remembers Roddam Narasimha

12-15-20

Caltech Distinguished Alumnus, Roddam Narasimha, passed away on December 14, 2020, at the age of 87. Dr. Narasimha received his Ph.D. (1961) in Aeronautics from Caltech. He was a faculty member at the Indian Institute of Science, and more recently, the Year-of-Science Chair Professor at the Jawaharlal Nehru Centre for Advanced Scientific Research. He was also a former director of the Indian National Aerospace Laboratories. Narasimha was a Clark B. Millikan Visiting Professor and a Sherman Fairchild Distinguished Scholar at Caltech. He made outstanding and wide-ranging scientific contributions in fluid mechanics and aerodynamics, and was internationally known for his research in turbulence with applications in geophysical fluid dynamics and atmospheric sciences. Narasimha was a foreign member of the U.S. National Academy of Engineering and the National Academy of Sciences, and a fellow of the Royal Society. [Obituary]
