I am an Assistant Professor at Uppsala University, Department of Mathematics. I am part of the group Analysis and PDEs led by Professor Kaj Nyström. My research is suported by WASP, The Wallenberg AI, Autonomous Systems and Software Program.

Research interests

My research is concerned with exploring various aspects of PDEs and their connection to Deep Learning. Originally my research focused on the regularity and existence theory of nonlinear diffusion equations, but I have later broadened my interests to include other equations such as the Monge-Ampère equation and approximation of solutions using neural networks.
