Research:

**Interests**: nonlinear PDE, optimal transport, calculus of variations, and numerical analysis.

**Projects**: NSF DMS-1811012, Singular Limits of Gradient Flows: Analysis and Numerics

**Slides from recent talks**: can be found on my curriculum vitae.

**Academic Bio:** 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.
