Lars Niedorf

I am a Van Vleck Assistant Professor at the University of Wisconsin-Madison under the mentorship of Andreas Seeger. I received my PhD from Kiel University in February 2024 . My advisor was Detlef Müller.

My main research interests lie in harmonic analysis and PDEs, in particular non-commutative harmonic analysis on Lie groups, spectral multipliers for subelliptic operators, and wave equations.
