Minghui Ouyang

About

My name is Minghui Ouyang(欧阳铭晖 in Chinese). I'm currently pursuing a Ph.D. in Mathematics at Peking University, China, advised by Prof. Chunwei Song. I received my B.S. from Peking University with a double major in Mathematics and Computer Science in 2021. My research interests lie in combinatorics and theoretical computer science.
