associate professor
Beijing Normal University
Research Interests

Inspired by recent progress in quantum coherent effects in biology, I mainly focus on the topic concerning quantum coherent device.

I am now an associate Professor. I received my Ph.D in physics from Department of Physics, Tsinghua University in July 2009. Then, I persued my research as post-doctoral research associate in Institute of Theoretical Physics in Chinese Academy of Sciences. In Nov. 2011, I continued my post-doctoral research in Department of Chemistry, National Taiwan University. At present, I have switched all my attention to the quantum coherence signature in natural light-harvesting process discovered recently. We believe that the intrinsic mechanism of high efficiency in green plants and bacteries would shew light to the design of artficial devices to capture solar energy, which may be an alternative solution to energy problems in future.
