### About Me

I graduated in May 2018 from Brown University, where I worked under the supervision of George Daskalopoulos. In the fall of 2018 I will be visiting the IAS for their program "Variational Methods in Geometry," and in the spring of 2019 I will return to Brown University as an instructor.

### Research

I am interested in applications of harmonic maps between singular statements. Some of these applications lie in rigidity statements for spaces of curvature bounded above, while others are in Teichmuller theory.
