As a member of the research group Applied Mathematics and Modeling, I just finished my PhD thesis in mathematics supervised by Ulisse Stefanelli. During my doctoral studies in mathematics, I have also been part of the Vienna School of Mathematics, the project Variational Modeling of Molecular Geometries, the doctoral program Dissipation and Dispersion in Nonlinear PDEs, and the special research program Taming Complexity in Partial Differential Systems (project Multiphysics Effects in Solids). Moreover, I am teaching at the University of Applied Sciences Technikum Wien.
