I am a final-year PhD student at the Hong Kong University of Science and Technology, co-supervised by Prof. Yi Yang and Prof. Yangqiu Song. Previously, I received my MS degree from the Chinese University of Hong Kong and my BS degree from Sun Yat-sen University.

I will join Tencent Lightspeed Studios after graduation.
