Hayan nam
I am a postdoctoral scholar at Iowa State University and my mentor is Steve Butler. I got my Ph.D. at University of California, Irvine with my advisor Nathan Kaplan. I am interested in Combinatorics and Number Theory. My research focuses on core partitions, integer partitions, numerical semigroups, and their geometric descriptions and applications using Ehrhart theory.
