Atomic Fractals in Metallic Glasses


Julia R. Greer, Professor of Materials Science and Mechanics, and colleagues including graduate student David Chen have shown that metallic glasses has an atomic-level structure although it differs from the periodic lattices that characterize crystalline metals. "Our group has solved this paradox by showing that atoms are only arranged fractally up to a certain scale," Greer says. "Larger than that scale, clusters of atoms are packed randomly and tightly, making a fully dense material, just like a regular metal. So we can have something that is both fractal and fully dense."

New EAS Division Chair Announced


Guruswami Ravichandran, John E. Goode, Jr., Professor of Aerospace and Mechanical Engineering; Director, Graduate Aerospace Laboratories, has been selected as the new chair of the Division of Engineering and Applied Science (EAS) effective September 1, 2015. "I believe, based on the evaluation of the search committee and on my own interactions with him, that Ravi not only has the judgment, energy, and vision to lead the division creatively and effectively, but that he will also be an outstanding advocate for the division," said Edward Stolper, Carl and Shirley Larson Provostial Chair and William E. Leonhard Professor of Geology, in an announcement to the EAS faculty. Professor Ravichandran commented, "During my tenure, I would like to see that we attract the best faculty and students to EAS and the Institute who will enable interdisciplinary activities across Caltech and contribute to frontiers of engineering science and technology. I would like to see a more diverse body of students and faculty, who will enrich EAS and the Institute, and I would like to see EAS be at the forefront of technological revolution based on our unique ability to drive advances through basic research.” [Caltech Release]

Preparing for Earthquakes with ShakeAlert


United States Geological Survey (USGS) has announced an approximately $4 million in awards to Caltech, University of California Berkeley, the University of Washington and the University of Oregon, for the expansion and improvement of the ShakeAlert, an earthquake early-warning system. "Caltech's role in ShakeAlert will focus on research and development of the system so that future versions will be faster and more reliable," said Professor Thomas Heaton. "We currently collect data from approximately 400 seismic stations throughout California. The USGS grant will allow Caltech to upgrade or install new stations in strategic locations that will significantly improve the performance of ShakeAlert." [Caltech story]

Vedran Coralic Receives 2015 Richard B. Chapman Memorial Award


Vedran Coralic, a graduate student working with Professor Tim Colonius, is the recipient of the 2015 Richard B. Chapman Memorial Award. Dr. Coralic performed numerical simulations of shocked-bubble dynamics in the microvasculature in order to characterize the mechanisms of tissue injury resulting from the collapse of preexisting bubbles in shockwave lithotripsy. The Richard B. Chapman Memorial Award is given to an EAS graduate student in hydrodynamics who has distinguished himself or herself in research.

Srivatsan Hulikal Wins Seismo-Engineering, Prediction, and Protection Prize


Graduate student, Srivatsan Hulikal, was the recipient of the the 2015 Demetriades - Tsafka - Kokkalis Prize in Seismo-Engineering, Prediction, and Protection. In his thesis, Dr. Hulikal successfully took on the multifaceted and challenging problem of linking macroscopic frictional properties of interfaces to their micromechanics. His advisor Professor Lapusta explains, “Understanding this connection is key to addressing fundamental problems in seismo-mechanics and seismo-engineering, such as creating predictive physical models of earthquakes.”

Charles C. Gates Jr.–Franklin Thomas Laboratory


The Charles C. Gates Jr.–Franklin Thomas Laboratory, the newly renovated home of the Department of Mechanical and Civil Engineering and the administrative offices for the Division of Engineering and Applied Science, was officially dedicated with an opening ceremony on Monday, June 1. The renovation includes the building's original iron railings as well as artistic etchings and imagery that reference prior research in earthquake engineering and hydrodynamics. Looking to the future, the energy-efficient, renovated building features state-of-the-art laboratories and experimental and computational facilities, along with open spaces where faculty, scholars, and students can share ideas across disciplines.
