Starting from Fall 2019, I am a Professor of Mathematics at Caltech. From Fall 2015 to Summer 2019, I was an Assistant Professor in the Department of Mathematics at University of Wisconsin-Madison. Prior to that I spent one year as a Chapman Fellow of Mathematics at Imperial College London. From Fall 2011 to Spring 2014, I was a J.J. Sylvester Assistant Professor in the Department of Mathematics at Johns Hopkins University, taking a leave in Fall 2011 at Mathematical Sciences Research Institute (MSRI) as a postdoctoral fellow.
I graduated from MIT in June 2011 with a Ph.D. in mathematics under the direction of Tobias H. Colding. I earned a B.S. in mathematics from Peking University in July 2006 under the direction of Zhangju Liu.
My primary research interest is geometric analysis -- more specifically, geometric flows (mean curvature flow, Ricci flow, and harmonic map heat flow) and related topics, such as minimal surfaces and low-dimensional topology.
My work is currently supported by the NSF grants DMS-2018220 and DMS-2018221.
