Research Interests/Scholastic Profile

  • I am interested in low-dimensional topology and geometry, especially in geometric structures on 2- and 3-manifolds. Currently, I have been using a geometric complexity function to study topological and Riemann surfaces as branched covers of the Riemann sphere. I am also interested in exploring the connections of that complexity function to the classical Hurwitz problem.
