Group Leader


Dr. Renqiang Yang. He was conferred with the Ph.D. degree in 2004 in South China University of Technology and then did researches on organic opto-electronic materials in the University of California Santa Barbara, USA from 2004 to 2009. Over these years, he has been PI and coordinated nearly 10 Chinese and American scientific projects. He has published 40 papers in international journals, among which 38 was indexed by SCI. He has applied 1 Chinese patent and 2 USA patents. His main research areas include: synthesis organic opto-electronic materials and application on display, solar cell and biosensor. More...
