Research Interests

I will be a Visiting Assistant Professor in mathematics at the College of William and Mary from Fall 2011.
My research interests lie in graph theory , particularly extremal problems (on regular graphs), the relationship between graph parameters and eigenvalues, and structural graph theory, and my adviser is Douglas B. West.
