About Me
Since November 2024, I am a postdoctoral researcher at Université Paris Dauphine in the group of Mathieu Lewin.
Prior to this, I did my Ph.D. at IST Austria with Robert Seiringer and
my M.Sc. at the University of Copenhagen with Jan Philip Solovej.
My research interests are within the mathematics of many-body quantum systems
and effective theories thereof.
