Research

I am working in mathematical physics. I am interested in the mathematical analysis of both many-body quantum systems (such as bosonic and fermionic systems and the polaron) and their effective equations. On the one hand I am studying the mathematical description of Bose-Einstein condensates through central limit theorems and large deviation principles. On the other hand I am working on properties of the effective equations for polaron models and their derivation from the many-body quantum systems. For more details see my list of publications below.

Short CV

I completed my bachelor in physics at the University of Leipzig, and my master at the University Munich and the Technical University Munich in the frame work of the master program Theoretical and Mathematics Physics under the supervision of Heinz Siedentop. In 2019 I received my PhD at the Zurich Graduate School of Mathematics under the supervision of Benjamin Schlein. From 2019 to 2022 I was a postdoctoral fellow in the group of Robert Seiringer at the Institute of Science and Technology Austria. From 2022 to 2024 I was an interim professor at University Munich in the working group stochastics and financial mathematics. Since 2024 I am a postdoctoral researcher with Phan Thanh Nam .

Teaching WiSe 2023/24

I am teaching the course "Stochastik". Please register through moodle for the course.

Seminars

I am co-organizing the online GAuS Seminar on topics in mathematical physics, analysis and PDE together with Christoph Kehle (ETH Zurich) and Konstantin Merz (TU Braunschweig).

I am co-organizing the hybrid seminar TU-LMU young researcher seminar on topics in mathematical physics together with Lea Bossmann (LMU Munich) and Amanda Young (TU Munich).

Thematical semester "Optimal Transport on Quantum Structures"

I am co-organizing a thematical semester on Optimal transport on Quantum Structures at the Erdős Center (at the Rényi Institut in Budapest) together with Jan Maas (ISTA) Tamás Tiktos and Dániel Virosztek (Rényi Institut Budapest). In this framework we organize a School (September 19-23, 2022), a Workshop (September 26-30, 2022) and several focus events.
