Xiang-qiang Chu

 Dr. Xiang-qiang Chu received her Ph.D. degree in Nuclear Science and Engineering from Massachusetts Institute of Technology (MIT) and her B.S. and M.S. degrees in Physics from Peking University in China. After two years of postdoctoral research at Oak Ridge National Laboratory (ORNL), she joined Department of Physics and Astronomy at Wayne State University as an Assistant Professor in August 2012. Her research interests focus on probing the dynamics and conformational changes of biomolecules, nano-materials and their hydration water or surface water through neutron and X-ray scattering spectroscopy and computational simulations.
