Tim Gräfnitz

Since April 2022 I am a postdoctoral researcher at the University of Cambridge in the group of Mark Gross. I received my PhD in March 2021 from the University of Hamburg under supervision of Bernd Siebert. Here is my CV.

Research interests: Algebraic Geometry, Logarithmic Geometry, Tropical Geometry, Enumerative Geometry, Mirror Symmetry, Birational Geometry.

Tropical correspondence for smooth del Pezzo log Calabi-Yau pairs, arXiv:2005.14018, J. Alg. Geom. 31 (2022) 4, 687–749.
Theta functions, broken lines and 2-marked log Gromov-Witten invariants, arXiv:2204.12257, 2022.
The proper Landau-Ginzburg potential is the open mirror map (with Helge Ruddat and Eric Zaslow), arXiv:2204.12249, 2022.
