The key area of research is mathematical analysis, or more precisely the theoretical aspects of non-linear partial differential equations. The main focus is on the regularity theory for a wide class of singular and degenerate elliptic and parabolic equations. These equations are connected to many different applications, such as diffusion in highly non-homogeneous media and the motions of multi-phased fluids in porous media. Methods from harmonic analysis are applied extensively and the research is also conducted in non-smooth contexts, ultimately in metric measure spaces.
