I am an MCQST Distinguished Postdoc in the group of Phan Thành Nam in the field of mathematical physics. My research focuses on the analysis of quantum many-body systems, in particular on the behaviour of dilute Bose gases.

My CV is available here.


Together with Amanda Young and Simone Rademacher, I organize the LMU-TUM Junior Researcher Seminar.
