He received his Ph.D. in mathematics from Johns Hopkins University, and his undergraduate degree from Pomona College. His current research focuses on algebraic graph theory, specifically the theory of expander families. His book "Expander Families and Cayley Graphs: A Beginner's Guide," co-authored with Anthony Shaheen, is due to come out in Fall 2011 with Oxford University Press.
