I am a post-doctoral fellow in Bonn at the Max Planck Institute for Mathematics Bonn in the workgroup of Catharina Stroppel.
Previously, I was an Assistant Adjunct Professor at the UCLA Department of Mathematics in the work group of Raphaël Rouquier. My PhD advisor was Wolfgang Soergel at Mathematisches Institut der Albert-Ludwigs-Universität Freiburg. My CV. |

My research area is *geometric representation theory* and *motivic homotopy theory*,
where I am particulary interested in:

- algebraic groups and Lie algebras,
- Soergel bimodules and Koszul duality,
- categories of motivic sheaves,
- six functor formalisms.

In very broad strokes, the general philosophy behind this area could be described like this:

Representation theoryis a branch of mathematics concerned with the study of symmetrical objects, ranging from wallpapers with a repeating floral pattern to quantum-mechanical systems and automorphic forms. A powerful technique is to turn representation theoretic problems into questions about the shape or geometry of some space; this makes them amenable to methods from other areas of mathematics, as topology, algebraic or differential geometry, and one speaks ofgeometric representation theory.

Slides which outline a new K-theoretic perspective on Koszul duality and giving a potential definition for K-theoretic intersection cohomology complexes. They were used for a talk at the Geometric Representation Theory conference at the MPIM Bonn/Perimeter Institute (June 2020).

Notes for a talk giving an overview of different applications of motivic sheaves in geometric representation theory. They were used in talks in Oxford (September 2019), Kaiserslautern and Bochum (October 2019).

Slides motivating and sketching a category of mixed sheaves with coefficients in $\mathbb{F}_p$ constructed in joint work with Shane Kelly (see Publications). They were made for a talk at the Erwin Schroedinger Institute in Vienna (2017).

Slides motivating and stating some of the results of my PhD thesis. They were made for the investigation of our Graduiertenkolleg in June 2016 and also partly used in talks I gave in Regensburg (July 2016), Bonn (August 2016), Clermont-Ferrand (2017) and in my PhD defense.

Handwritten notes (thanks to Konrad Voelkel) of a joint talk with Florian Beck, explaining the relation between Verdier duality, Borel–Moore homology and cosheaves.

Slides describing the content of my master thesis developing a new algorithm for the computation of the Tutte polynomial of a matroid.

In 2019, I was awarded the Distinguished Teaching Award of the UCLA math department. | My hardworking students! |
