Welcome! I am a Junior Professor for Number Theory in the Algebra and Geometry Group at Goethe University Frankfurt am Main. My position in Frankfurt is supported by the LOEWE-Schwerpunkt Uniformized Structures in Arithmetic and Geometry. My research program is funded by DFG-Sachbeihilfe Grant Project No. 456557832 "From Riemann surfaces to tropical curves (and back again)".

My research interests are in combinatorial algebraic geometry with a particular focus on tropical and non-Archimedean geometry and the geometry of moduli spaces. I am happy to supervise two Ph.D.-students: Felix Röhrle and Pedro Souza.

From October 2018 until March 2019 I was a Marie Skłodowska-Curie Fellow at the University of Warwick, hosted by Diane Maclagan. Before coming to Frankfurt, I have been a Postdoc Assistant Professor at the Department of Mathematics at the University of Michigan, Ann Arbor, a postdoctoral fellow at the Fields Institute for Research in Mathematical Sciences within the thematic program on Combinatorial Algebraic Geometry as well as a Hausdorff postdoc at the University of Bonn in the group of Daniel Huybrechts. During Summer 2017 I have visited the Research Group in Nonlinear Algebra, led by Bernd Sturmfels, at the Max Planck Institute of Mathematics in the Sciences, Leipzig.

I completed my doctorate at the Department of Mathematics at Brown University with a thesis on the Tropical geometry of logarithmic schemes. My doctoral advisor was Dan Abramovich. I did my undergraduate degree in Mathematics with a minor in Physics at the University of Regensburg, where I wrote an undergraduate thesis under the guidance of Klaus Künnemann. During this time I also spent a year as a visiting graduate student at Brandeis University.


Jobs at the new CRC 326 - GAUS.

There are several openings for Ph.D. and Postdoc positions at the newly established Collaborative Research Center 326: Geometry and Arithmetic of Uniformized Structures (GAUS) at its various locations.

A regular afternoon seminar series on tropical geometry and neighboring fields (currently held via Zoom). The next few dates are the following:

  • 30. April 2021

  • 28. May 2021

  • 25. June 2021

My co-organizer is Lorenzo Fantini.

A workshop at Goethe University Frankfurt, Sept. 14-17, 2020. My coorganizers are Lorenzo Fantini and Annette Werner. *Postponed due to the CoViD19 pandemic*
