About Me

Hi! I am Xun Wang (汪洵 in Chinese).

I am currently a first-year Ph.D. student at Institute for Interdisciplinary Information Sciences (IIIS), Tsinghua University, where I am fortunate to be advised by Prof. Longbo Huang. Prior to this, I earned a Bachelor of Science degree from Nanjing University in 2024.

I am generally interested in AI for Decisions, especially for Reinforcement Learning (RL) algorithms and their applications.
