am associated with the Department of Mathematics
and the Institute for Computational Engineering and Sciences (ICES) in the
of Texas at Austin. I got my PhD from Columbia University in 2006 and spent a
year in The University of Chicago as a L. E. Dickson instructor in Applied Mathematics before joining UT Austin in Fall 2008.
I am interested in applied and computational mathematics in general. My recent research are mainly on: inverse problems to PDEs, mathematical imaging, kinetic equations, and random graphs. Below are some of my recent publications. A full list of my publications can be found here.
