I am a Tamarkin Assistant Professor in the Department of Mathematics at Brown University. Prior to coming to Brown, I received my Ph.D. in Mathematics from University of Maryland – College Park in 2012. Here is my CV. I am co-organizing the Brown PDE seminar with Yan Guo. Here is the PDE seminar schedule.
