# About me

I got my PhD from Johns Hopkins University in 2009. From 2009-2012 I was a CLE Moore instructor at MIT, and I spent the fall of 2010 as a postdoc at the MSRI program on inverse problems. I am currently an associate professor at University of California, Irvine.

My research is in analysis and partial differential equations. I am especially interested in semiclassical/microlocal analysis and its applications in PDE and mathematical physics, in particular spectral geometry and quantum chaos.
