During fall quarter 2016, I taught Math 117, Methods of Analysis.


I am interested in nonlinear PDE, optimal transport, calculus of variations, and numerical analysis.

I received my Ph.D. at Rutgers University, where my advisor was Eric Carlen. I spent the first year of my NSF postdoc at UCLA, where my postdoctoral mentor was Andrea Bertozzi. I then spent a year at UCSB as a UC President’s Postdoctoral Fellow, under the mentorship of Bjorn Birnir. I am now an assistant professor at UCSB.

On my curriculum vitae, I link to slides from recent talks I have given.
