I am a PhD candidate at CSD, working currently in the MaPSI project.

After finishing my master's degree in Engineering Mathematics at TU Graz, I moved to Bergen and started my research in August 2021.

My interests include Porous Media Flow Modelling and Simulation, including Multiphase-Multicomponent Flow and Fractures. Associated numerical challenges are part of the fun. Our group is working on an open-source Python package for this field, PorePy. Related implementations can be found there.
