About Me

CV (Updated 2023 March 22)

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. I am partially supported by the Natural Sciences and Engineering Research Council of Canada (NSERC), [funding reference number PGSD-568936-2022]
