Research Interests

My research interests are in geometric analysis, geometric group theory, and geometric topology. These areas involve a mixture of ideas from geometry, analysis, topology, and algebra. Current research topics include:

  • Geometric evolution equations: Ricci flow and mean curvature flow.
  • Quasi-isometric rigidity.
  • Quasisymmetric structure of self-similar spaces, such as boundaries of hyperbolic groups.
  • Bilipschitz embedding problems.
  • Analysis on singular spaces, e.g. Carnot groups, and spaces satisfying Poincare inequalities.
