College of Physics & Center for Nanochemistry, Peking University, Beijing, China  

Professional Experience：
  2014-now：Principal Investigator, College of Physics, Peking University
  2009-2014：Postdoctoral Researcher, Prof. Feng Wang group, Department of Physics, UC Berkeley, US

Education：
  2004-2009：PhD, Institute of Physics, Chinese Academy of Sciences, Supervisor: Prof. Enge Wang
  2000-2004: Bachelor, Department of Physics, Beijing Normal University

Research：
  Investigation of novel physical phenomena emerging in individual quantum structures, especially 1D carbon nanotubes system and 2D atomic layers system, by applying advanced single quantum-material level in-situ Nano-optics + TEM  techniques. Current research interests are:

 (1) Development of in-situ high contrast ultrafast nano-optics + TEM system
 (2) Electronic and mechanical coupling in van der Waals 1D and 2D materials
 (3) Ultrafast energy and electron transfer in low-dimensional materials
 (4) Interaction between water and 1D carbon nanotubes
 (5) In-situ micro-CVD growth
