I am a faculty member at the School of Mathematical Sciences, University of Science and Technology of China (USTC).

I was a Hedrick Assistant Professor at the Department of Mathematics, UCLA, and a Postdoctoral Associate at the Department of Mathematical Sciences, Carnegie Mellon University. I obtained my Ph.D. degree in 2011 from the School of Mathematics, Georgia Institute of Technology, under the supervision of Prof. Xingxing Yu. Back in 2007, I recieved my B.S. degree from the School of Mathematical Sciences, USTC. For more information please see my Curriculum Vitae as below.

I received The National Science Fund for Excellent Young Scholars (国家自然科学基金委优秀青年基金) in 2016. I am an associate editor at SIAM Journal on Discrete Mathematics since 2018.
