## Research Information

### Research Interests

My research area is geometric analysis. I am interested in the connection between inequalities in analysis and their geometric implications, and also in quasiconformal maps and the geometric properties of metric measure spaces conserved by them. I am also currently interested in the geometry behind the theory of functions of bounded variation (BV) and Besov spaces, and I am also interested in various notions of boundary in potential theory, and in the study of transformations of metric measure spaces that preserve bounded geometry.
