Welcome! I am a Junior Professor for Number Theory in the Algebra and Geometry Group at Goethe University Frankfurt am Main and a Principal Investigator at the newly established SFB 326 - GAUS. My research program is also funded by DFG-Sachbeihilfe Grant Project No. 456557832 "From Riemann surfaces to tropical curves (and back again)". Until 2022, my position in Frankfurt was supported by the LOEWE-Schwerpunkt Uniformized Structures in Arithmetic and Geometry.

My research interests are in algebraic geometry, with a particular focus on tropical geometry and moduli spaces, logarithmic and non-Archimedean geometry, matroids and buildings, vector bundles and principal bundles and, in general, on combinatorial algebraic geometry.

### Short Bio

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 was a Postdoc Assistant Professor at the Department of Mathematics at the University of Michigan, Ann Arbor, mentored by Mattias Jonsson, 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 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.

### Mathematics is for everyone!

I strongly support the axioms laid out by Federico Ardila.

Mathematical potential is distributed equally among different groups, irrespective of geographic, demographic, and economic boundaries.

Everyone can have joyful, meaningful, and empowering mathematical experiences.

Mathematics is a powerful, malleable tool that can be shaped and used differently by various communities to serve their needs.

Every student deserves to be treated with dignity and respect.
