About me

I am Yi Han, a Ph.D. candidate and a photographer.

I am in the Department of Control Science and Systems Engineering at Peking University in Beijing, China. My research focuses on mathematical modeling and analysis of multi-agent systems, drawing on dynamical systems, fairness, and game theory to study interaction, resource allocation, and collective outcomes.

Photography is a parallel practice of observation and memory. This portfolio gathers everyday landscapes, quiet structures, and the traces people leave behind, along with occasional notes about the places and ideas around them.
