I’m currently an assistant professor at CMU. I got my PhD at Columbia in 2014 then spend three years as a postdoc at Stanford. My research interest lies in the general areas of partial differential equations and probability, with focuses on stochastic homogenization, wave propagation in random media, and SPDE. I was a research member of MSRI in fall 2015. My research is supported by NSF grant DMS-1613301.
