# About me

**E-mail:** Last name followed by “hao” at nus dot edu dot sg

**Office:** 07-06, S17 Department of Mathematics, NUS.

**Field of interest:** extremal combinatorics, probabilistic/algebraic methods, spectral graph theory, structural graph theory, and applications in theoretical computer science.

**A brief biosketch:**

Currently I am a Dean’s Chair Associate Professor at National University of Singapore.

Before joining NUS, I was a tenure-track Assistant Professor from 2015 to 2021 (tenured in 2021) in the Department of Mathematics at Emory University. As a postdoc (2012-2015), I enjoyed the hospitality of Institute for Advanced Study in Princeton, DIMACS at Rutgers University, Institute for Mathematics and its Applications at UMN.

I completed my B.S. degree in School of Mathematical Sciences, Peking University back in 2007. I received my Ph.D. degree in June 2012, from Department of Mathematics, UCLA, advised by Professor Benny Sudakov. (Click for a nice photo of our combinatorics group at UCLA).
