Brief:

I started PhD study in Chinese Academy of Sciences (CAS) in 2004, with Prof. Yonghai Chen (PhD supervisor) in the Institute of Semiconductors. From 2006 to 2009 I was selected in the first Chinese Academy of Sciences - Max Planck Society joint PhD program, working partly in Stuttgart (MPI-FKF) and Dresden (IFW). Part of my PhD study was performed together with Prof. Val Zwiller in Kavli Institute of Nanoscience, Delft University of Technology, The Netherlands.

After the PhD I did one and half year Postdoc with Oliver and Armando, then I got the support from Marie Curie Fellowship and moved to Switzerland. During the two years' stay in Big Blue (IBM) I was working with Dr. Rainer F. Mahrt in the Exploratory Photonics Group. Since October 2012 I returned to IFW as a scientific group leader.
