About Me

I am a post-doctoral researcher at the Max-Planck Institute for Mathematics in the Sciences in Leipzig, supervised by Guido Montufar and Bernd Sturmfels. I completed my PhD in Mathematics at TU Berlin under the supervision of Martin Skutella. My research focuses on neural networks theory using polyhedral geometry, combinatorics, computational complexity and topology. I previously earned a B.Sc. in Mathematics and Computer Science and an M.Sc. in Mathematics from the University of Greifswald
