About

Picture

I am a postdoc in the BIREP group at Bielefeld University. I spend the academic year 2023/24 at the University of California, Los Angeles, funded by a Feodor Lynen Research Fellowship by the Humboldt foundation.

In 2020 I obtained my PhD from 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.

My research lies in the areas of commutative algebra and representation theory of finite dimensional algebras. I am interested in triangulated, derived, and stable categories.

Here is my CV.
