I am a postdoc at the University Bielefeld, Germany, in the BIREP group.

In 2020 I finished my PhD at the University of Utah. There I studied commutative algebra with Srikanth Iyengar. The title of my thesis is Generation Time in Derived Categories.

I obtained a Bachelor in Mathematics in 2014 and a Bachelor in Physics in 2015 from the Johannes Gutenberg University Mainz, Germany.

I am interested in triangulated, derived, and stable categories.

Here is my CV.

- BRIDGES

Together with Allechar Serrano López, Christian Klevdal, Peter McDonald and Sabine Lang I am organizing the conference BRIDGES for June 16–18, 2021. This conference is aimed towards early graduate students and advanced undergraduate students interested in representation theory, number theory, and commutative algebra.
