Research interests
All my papers (journal publications and preprints) are available at arXiv.org.
Here are reviews of my papers at mathscinet.ams.org.
Funding
My research has partially been funded by the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG) within two projects on curvature flows:
- "Harnack inequalities for curvature flows and applications", 2016-2019, gepris:319506420
- "Quermassintegral preserving local curvature flows", 2019-2020, gepris:400729345
Visibility
Over the past years I have presented my work at various places, including Harvard, Rutgers, Columbia (USA), McGill (Canada), Warwick (UK), Macquarie University Sydney (Australia) and Xiamen (China).
For a full list of talks and attended conferences see my personal webpage.
Supervision
In general I am interested in supervising PhD students in the areas of:
- Partial differential equations, with possible applications in
- Geometric evolution equations (mean curvature flow, Ricci flow and their friends)
- Hypersurface geometry (Stability of soap bubbles, theory of convex bodies, isoperimetric inequalities)
- Lorentz geometry and general relativity
Past projects
- Project leader of the project "Harnack inequalities for curvature flows and applications", funded by the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG), 2016-2019, gepris:319506420
