Anthony B. Hmelo

Research Assistant Professor of Materials Science

Education

State University of New York at Stony Brook
In 1987 Dr. Hmelo completed his dissertation entitled, "Characterization of Crack-tip Microstructures via Synchrotron Fractography in Mo and Mo-Nb Alloy Single Crystals." While pursuing graduate studies, he served as the research engineer for the Synchrotron Topography Project, and was responsible for the design and construction of an x-ray topography beam line (X19C) at the National Synchrotron Light Source, Brookhaven National Laboratory. He helped develop the White Beam Camera, a multi-user facility for the utilization of high intensity white beam radiation. He is the author of several articles on the application of x-ray topography and x-ray tomography to the characterization of materials.

He joined the Center for Microgravity Research and Applications at Vanderbilt University in 1988. In addition to his research activities, he has continued to design laboratory instrumentation for materials research, including the Hybrid Electromagnetic-Acoustic Levitator, and the High-Gravity Centrifuge at Vanderbilt University.

During 1995, he participated in the United States Microgravity Laboratory-2 (USML-2) spacelab mission as a co-investigator and engineer in support of the operation of the Drop Physics Module (DPM).
