Research Interests

I work on various topics in geometric and global analysis on manifolds and graphs, e.g., spectral and geometric implications of Ricci curvature bounds, properties of solutions to the heat and Laplace equation, and related topics. Besides this, I am interested in non-linear problems such as harmonic heat or mean curvature flow.
