Research Interests

Broadly my research interests are in theoretical computer science. I am currently looking into
  • Computational Geometry and Topology

  • Discrete and Combinatorial Geometry

  • Applied Probability Theory

  • Optimization Problems in Geometry and Graph Theory
During my PhD I worked on manifold reconstruction from dense point sample, sampling and 
triangulating submanifolds, stability of Euclidean Delaunay triangulations and intrinsic Delaunay 
triangulation of smooth manifolds.
