I am currently a SEW Assistant Professor in the Department of Mathematics at UC San Diego, working with Prof. Ming Xiao. Before that, I was a J. J. Sylvester Assistant Professor in the Department of Mathematics at Johns Hopkins University, working with Prof. Bernard Shiffman. I received my PhD in 2016 from Department of Mathematics from University of California, Irvine, under Prof. Zhiqin Lu.

 

My research field is Kahler geometry. I am mainly interested in Bergman kernel and L2 estimates. 

 

Teaching

Winter 2020: Math 142A, Introduction to Analysis I.

Fall 2019: Math 20C, Calculus & Analytic Geometry For Science & Engineering.
