Since August 2019, I am an NSF Postdoc and L.E. Dickson Instructor at the University of Chicago.

From September 2018 to July 2019, I was a member at the Institute for Advanced Study during the Sepcial Year on Variational Methods in Geometry . My mentor was Prof. Camillo De Lellis .

In June 2018 I graduated from the University of Washington, and my advisor was Prof. Tatiana Toro.

You can find my CV here .

Broadly speaking my work lies in the intersection of Geometric Measure Theory, Geometric Analysis, PDEs and Harmonic Analysis.

In particular I am interested in regularity problems of minimal surfaces and area-minimizing currents; unique continuation problems; the properties of the harmonic and elliptic measures and their relations to elliptic boundary value problem.
