Former Caltech Postdoc Receives Israel Prize
Mordechai (Moti) Segev, a former postdoctoral fellow in Professor Amnon Yariv's group, will be receiving the Israel Prize for Physics and Chemistry. Dr. Segev is receiving the prize for ground-breaking research in the field of optics and lasers. "I am naturally proud of the achievements of former students and postdocs who started their scientific career in my group," says Professor Yariv. "Among this group Moti has become, in the relatively short time since leaving us, one the best known and influential scientists in the world in the field of quantum electronics and its amazing offspring of nonlinear optics. I am looking forward to a continuing stream of intellectual and experimental innovation flowing from him and his research group at the Technion."
Caltech Names Ninth President
Thomas F. Rosenbaum has been named the ninth president of Caltech. Dr. Rosenbaum, is currently the John T. Wilson Distinguished Service Professor of Physics at the University of Chicago, where he has served as the university's provost for the past seven years. Also joining Caltech and the EAS Division will be Dr. Rosenbaum's spouse, Katherine T. Faber, the Walter P. Murphy Professor of Materials Science and Engineering at Northwestern University. Professor Faber's research focuses on understanding stress fractures in ceramics, as well as on the fabrication of ceramic materials with controlled porosity, which are important as thermal and environmental barrier coatings for engine components. She is also the codirector of the Northwestern University-Art Institute of Chicago Center for Scientific Studies in the Arts (NU-ACCESS), which employs advanced materials science techniques for art history and restoration.

Spirals of Light May Lead to Better Electronics
Kerry J. Vahala, Ted and Ginger Jenkins Professor of Information Science and Technology and Applied Physics as well as Executive Officer for Applied Physics and Materials Science, and colleagues have created the optical equivalent of a tuning fork—a device that can help steady the electrical currents needed to power high-end electronics and stabilize the signals of high-quality lasers. They were able to stabilize the light's frequency by developing a silica glass chip resonator with a specially designed path for the photons in the shape of what is called an Archimedean spiral.

Julia R. Greer, Professor of Materials Science and Mechanics, and colleagues have created nanostructured, hollow ceramic scaffolds, and have found that the small building blocks, or unit cells, display remarkable strength and resistance to failure despite being more than 85 percent air. The general fabrication technique the researchers have developed could be used to produce lightweight, mechanically robust small-scale components such as batteries, interfaces, catalysts, and implantable biomedical devices.
