Speaker: Professor Thomas Zega, University of Arizona
Date: May 30, 2019 Time: 1:30 PM Location: BSB 147
Thomas Zega is Associate Professor in the Lunar and Planetary Laboratory and the Dept. of Materials Science and Engineering at the University of Arizona. He is the Scientific Director of the Kuiper Materials Imaging and Characterization Facility at the University of Arizona and the PI of the planetary-materials research group that examines those pieces of condensed matter that were leftover from the time that our solar system formed over 4.5 billion years ago. His current research efforts are focused on: the origin of the presolar grains, nm to μm-sized dust particles that formed inside of ancient stars but preserved inside of primitive meteorites; the structure and crystal chemistry of 4.6-billion-year-old refractory inclusions in meteorites that are the first solar-system solids; the functional chemistry and preservation state of primitive pre-biotic organic compounds that formed in the early solar system and interstellar space; and the development of analytical techniques for investigations of such materials. Prior to joining the University of Arizona, he was a National Research Council Postdoctoral Fellow and later staff scientist at the Naval Research Laboratory, Washington DC, where his work focused on using electron microscopy to investigate spintronic materials, catalysts, photovoltaic materials, and the origins of planetary materials.
