Ph.D. (South China University of Technology)

Visiting Ph.D. (Imperial College London)

B.S. (South China University of Technology)

Dr. Yan obtained his B.Eng. in 2012 and his Ph.D. in 2018, both from the South China University of Technology (SCUT). His doctoral research was supervised by Professors Hongbin Wu and Yong Cao. From 2019 to 2022, he worked as a postdoctoral researcher in the Department of Physics at Imperial College London within Professor Jenny Nelson’s group. In 2023, he joined The Chinese University of Hong Kong, Shenzhen as an Assistant Professor.

Dr. Yan's research focuses on device physics and modelling, employing a combined theoretical and experimental approach to elucidate the fundamental mechanisms of organic molecular optoelectronic devices—primarily photovoltaics and photodetectors. His work has been published in leading scientific journals, including Nature Materials, Physical Review X, and Nature Communications.
