Prof. Chen received his B.S. degree from University of Science and Technology of China in 2000 and his Ph.D. degree in condensed matter physics from Purdue University in 2007. He worked as a post-doctoral fellow at University of California, San Diego (UCSD) before he moved to the Materials Science Division of Lawrence Berkeley National Laboratory in 2011. From 2012 to 2015, full professor at Shanghai Synchrotron Radiation Facility, Shanghai Institute of Applied Physics, Chinese Academy of Sciences. Since January of 2015, he joined the School of Physical Science and Technology of ShanghaiTech University as an assistant professor、PI.

Research Interests
We apply a broad range of X-ray and optical techniques, including X-ray diffraction, scattering and absorption, FTIR, and Raman spectroscopy, to study nanoscale and energy-related materials.
