Leonard Schmitz

I am a PhD student at the University of Greifswald under the supervision of Prof. Joscha Diehl.
Before that, I received my Master at the RWTH Aachen.

My work is supported by the trilateral project EnhanceD Data stream Analysis with the Signature Method of the ANR-DFG-JST.


From April 2024, I will be postdoc in the nonlinear algebra group of Bernd Sturmfels at the Max Planck Institute for Mathematics in the Sciences, Leipzig.
