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 position in Frankfurt is supported by the LOEWE-Schwerpunkt Uniformized Structures in Arithmetic and Geometry and my research program is also funded by DFG-Sachbeihilfe Grant Project No. 456557832 "From Riemann surfaces to tropical curves (and back again)".

My research interests are in algebraic geometry, with a particular focus on tropical geometry and moduli spaces, 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.

We are organizing a workhop on Newton-Okounkov bodies and tropical geometry on Nov. 14 - Nov. 18. See here for more information

SFB 326 - GAUS

The SFB 326: Geometry and Arithmetic of Uniformized Structures​ (GAUS) has started in July 2021. Our group is involved in two projects.

Ruth Moufang Lectures

Jennifer Balakrishnan gave the inaugural Ruth Moufang Lectures on July 13-16. Check out our YouTube-Channel for videos of the talks.

A regular afternoon seminar series on tropical geometry and neighboring fields (currently held via Zoom).

My co-organizer is Andreas Gross. Check our YouTube Channel for videos of past talks.

A workshop at Goethe University Frankfurt, originally scheduled for Sept. 14-17, 2020. My co-organizers are Lorenzo Fantini and Annette Werner. This is now a series of virtual and hybrid afternoon workshops starting on Oct. 1, 2021 similar to the TGiZ.

A virtual Mini-Workshop organized together with Alex Küronya and Duco van Straten on June 11, 2021.
