I got my B.S. in 2010 from Harbin Institute of Technology (China), majoring in Optoelectronics. Then I continued my Ph.D. study in Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, focusing on organic heterojunctions and their applications in high performance organic light emitting diodes (OLEDs). 
After receiving my Ph.D. degree in 2015, I joined Laboratory of Organic Electronics (LiU) in 2016 as postdoctoral researcher. My research topics here mainly involve doping of conducting polymers, and related thin film organic nanoelectronic devices.
