About me:
I’m an assistant professor at CMU. I got my PhD at Columbia in 2014 and did a postdoc at Stanford in 20142017. I was a research member of MSRI in fall 2015.
I work on PDE and probability, with a focus on stochastic homogenization, wave propagation in random media, and SPDE.
My research is supported by NSF grant DMS1613301/1807748 and by the Center for Nonlinear Analysis of CMU.
