Biography

Dr. Yan received his B.Eng. in 2012 and Ph.D. in 2018 (supervised by Prof. Hongbin Wu and Prof. Yong Cao) both at South China University of Technology. He was a key member in Prof. Jenny Nelson’s group between 2017 and 2022, and currently an academic visitor in Department of Physics at Imperial College London. He joined The Chinese University of Hong Kong, Shenzhen as a tenure-track assistant professor in May 2023. His research focuses on using combined theoretical and experimental approaches to understand the device and molecular physics of organic molecular optoelectronic devices, including photovoltaics, light-emitting-diodes, and photodetectors.
