I’m a Ph.D. candidate at Academy of Mathematics and Systems Science, Chinese Academy of Sciences (AMSS, CAS). My current research focuses on quantum algorithms and quantum complexity theory, especially query complexity. I am also broadly interested in other topics in quantum information science, particularly those with deep mathematical foundations, with the overarching goal of better understanding the structure of quantum advantage.

I’m currently looking for a postdoc position :)
