BIOGRAPHY

Qian Gong received the B.S. degree in applied physics from Beijing Normal University in 1993,  and the PhD degree from Institute of Semiconductors, Chinese Academy of Sciences, in 1998. From 1999 to 2001, he was with the Paul Drude Institute for Solid State Electronics, Berlin, Germany, where his research involved investigation of molecular-beam epitaxy of low-dimensional semiconductor structures on patterned substrate and high index surfaces. From 2001 to 2004, he was with COBRA Inter-University Research Institute, Eindhoven University of Technology, Eindhoven, The Netherlands, studying the growth mechanism and optical properties of self-organized quantum dots. In 2004, he joined the Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences, financially supported by Hundred-Talent project. In 2017, he joined ShanghaiTech University. His current research interests include DFB semiconductor lasers, tunable external cavity lasers, and molecular-beam epitaxy of low-dimensional semiconductor structures.
