Brief Research Summary
My research area lies in the intersection of Geometric Measure Theory, Analysis and Differential Geometry.
More precisely, the problems I am interested are in the GMT set up and I use geometric analysis tools such as Almgren-Pitts min-max and analysis of singularities to study variational objects such as minimal submanifolds, surfaces of constant mean curvature and self-shrinking surfaces of the mean curvature flow.
