I am interested in Discrete Geometry. Specifically, I study discrete configurations of points, circles, and spheres. I am motivated by endeavors to characterize circle packings and projective polyhedra up to Möbius transformations. Currently, I am exploring global rigidity (uniqueness); in the next phase of my research, I will focus on existence. I aim to use this as a path into studying projective structures on manifolds.


Here are a few powerpoints from talks I've given in the past year. I frequently give chalk talks.
