About me

Starting in the fall 2021, I will work as a Bonn Junior Fellow at the University of Bonn. Previously, I was employed as a Benjamin Peirce Fellow at Harvard University, where I have been working with Horng-Tzer Yau. I received my Ph.D. in 2018 from the University of Zurich, where my advisor was Benjamin Schlein. Here is my CV.

Research interests

My research area is mathematical physics. More specifically, I am interested in the analysis of many-body systems from quantum mechanics and statistical physics, such as Bose-Einstein condensates and spin glasses.

Teaching

In the fall 2021, I will be teaching a topics course on many-body quantum mechanics. A course syllabus can be found here.
