Summer term 21: Lecture Mean Curvature Flow and AG Seminar

I am interested in questions related to Geometric variational problems, for example minimal surfaces theory or Willmore surfaces.

• (with J. Hirsch) A note on Willmore minimizing Klein bottles in Euclidean space, Adv. Math. 319(2017), 67-75, available on Arxiv here.
• Singularities of the area preserving curve shortening flow with a Neumann free boundary condition, Math. Ann. 371(2018), no.3-4, 1429-1448, available on Arxiv here.
• The area preserving curve shortening flow with Neumann free boundary conditions, PhD Thesis, University of Freiburg, Faculty of Mathematics and Physics, 155p., 2014.

My preprints:

• (with J. Hirsch) On the Morse Index of Willmore Spheres, available on Arxiv here.
• (with J. Giesselmann) A posteriori error estimates for wave maps into spheres, available on Arxiv here.

I am member of the SPP 2026 „Geometry at infinity“, see SPP2026.

There is an open positions for a Post-Doc working in Geometric Analysis. It is an assistance position including some teaching duties. The desired start is fall 2021 or spring 2022.

If you are interested, please send me an Email. I am happy to provide more information.
