About me

Hi, I am Hongyin Chen. I am a last-year Ph.D. student at Peking University, advised by Prof. Xiaotie Deng. I’m currently visiting Dr. Ittay Eyal’s group at Technion. I obtained my Bachelor’s degree from the first Turing Class in EECS dept, Peking University.

My research interests are blockchain, mechanism design, algorithmic game theory, and reinforcement learning.
