Hsin-Yun Chao

Hsin-Yun (Joy) Chao is a UMD Post doctoral Researcher in the Nanoscale Imaging Group in the Nanoscale Device Characterization Division. She received a B.S. in materials science and engineering from the University of Illinois at Urbana-Champaign, a M.S.E. from The University of Michigan-Ann Arbor and is currently a doctoral candidate at the University of Maryland at College Park. Her doctoral research will focus on experimental and theoretical measurements to establish correlations between single-wall carbon nanotube structure and the atomic structure of catalyst nanoparticles. Joy is working with Renu Sharma and John Cumings on In-Situ Characterization of Nanoscale Gas-Solid Interactions using environmental transmission electron microscope ETEM) equipped with a Raman spectrometer.
