About Me

Most people call me Jason. Currently I am a graduate student in the Department of Mathematics at the University of Illinois Urbana-Champaign. I completed a Master of Mathematics (MMath) degree in Combinatorics and Optimization program at the University of Waterloo, supervised by Joseph Cheriyan and Yu-Ru Liu. Before this, I completed a BMath in Pure Mathematics/Combinatorics and Optimization at the University of Waterloo. My research interests are in sieve theory, graph theory, and enumeration.
