I am currently a Senior Researcher at NEC Laboratories America, headed by Professor Manmohan Chandraker. I graduated from National Univeristy of Singapore with Ph.D. degree in 2019, advised by Professor Loong Fah Cheong and Professor Gim Hee Lee. Before, I obtained my Bachelor's degree at University of Science and Technology of China (USTC) in 2015.
