About me

I am currently a Lecturer at Iowa State University. My research interests range over Combinatorics and Graph Theory. I am particularly interested in extremal problems in graph theory, including graph coloring, probabilistic method, etc. I graduated from University of Illinois under the guidance of Alexandr V. Kostochka.
