About me

Since Oct. 2021, I am a professor (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.

News

Open postdoc position: I would like to advertise an open postdoc position in my group, funded by the Hausdorff Center for Mathematics. The position comes with a competitive salary and the duration is of two years (with the possibility of an additional one-year reappointment), the precise starting date being flexible. Applicants should have a background in analysis and/or probability, with a strong interest in many-body systems from quantum mechanics and/or statistical physics. For more information, interested researchers are invited to contact me via email, including a current CV.
