Marius Nietschmann 

I am a PhD student in mathematics at Sorbonne Université and a member of the IMJ-PRG laboratory, under the supervision of Henrik Ueberschär and Maxime Ingremeau.

My research lies at the intersection of spectral theory, semiclassical analysis, and quantum chaos, with a particular focus on quantum graphs and the multifractal behavior of eigenfunctions and semiclassical measures. More broadly, I am interested in questions concerning localization, equidistribution, and the spectral properties of geometric and discrete operators.

Before starting my PhD in Paris, I studied mathematics at the University of Potsdam, where I worked on Hardy inequalities and fractional Laplacians.
