Dr. van Zyl Receives Honorary Doctorate
Dr. Jakob J. van Zyl (PhD ’86 EE), Caltech Senior Faculty Associate in Electrical Engineering and Aerospace, as well as the Associate Director of Project Formulation and Strategy at JPL, will receive an honorary Doctor of Engineering (DIng) degree from Stellenbosch University in South Africa. Dr. van Zyl was born in Outjo, Namibia and received his first degree in electrical engineering from the University of Stellenbosch . He then came to Caltech where he obtained his Masters and PhD in electrical engineering.

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."

Professor Bernardi Wins the Psi-K Volker Heine Young Investigator Award
Marco Bernardi, Assistant Professor of Applied Physics and Materials Science, has won the 2015 Psi-K Volker Heine Young Investigator Award. The award is given in recognition of an individual’s outstanding computational work in condensed-matter, materials, or nanoscience research involving electronic structure calculations. Professor Bernardi has received it for his research in first principles electronic structure calculations of the ultrafast dynamics of excited electrons in materials. His research is addressing the question of “how does an excited electron lose its energy?” which is central in a variety of fields ranging from condensed matter physics to electrical engineering and energy. Bernardi has developed and applied calculations to study the dynamics of out-of-equilibrium charge carriers, also known as hot carriers, in semiconductors and metals. [Learn more]
