My research field is geometric analysis. The main technical tool that I use is the theory of Sobolev spaces. I employ the theoy in various settings like analysis on metric spaces, calculus of variations, nonlinear elliptic PDE's, quasiconformal analysis, topology of mapping between manifolds and geometric measure theory.
