Hyojeong Son

Hello! I'm Hyojeong, a fourth-year graduate student in the Mathematics Department at the University of Washington, Seattle, working under Professor Christopher Hoffman. I specialize in discrete probability, focusing on particle models like activated random walks and sandpiles. Additionally, I explore stable matching problems, investigating the number of possible matchings based on different preference structures.

Welcome to my personal webpage! You can reach me at hjson@math.washington.edu, and my office is Padelford C-8K.
