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.
