About Me

I am currently a fifth-year PhD student in mathematics at New York University. I am graduating on May 2018. I will join Department of Mathematics at UCLA as a Hedrick Assistant Professor in Fall 2018.

I am interested in PDEs and numerical analysis arising in fluid dynamics in general. I am working with Prof. Fang-Hua Lin on PDEs in classic and complex fluids, and flow-structure interaction problems. I also worked with Prof. Michael Shelley on modeling and simulating active swimmers.

Before coming to NYU, I received B.S. in applied and computational mathematics in Peking University in July 2013.
Happy 120th Birthday, PKU!

Here is my CV.
