I am an assistant professor (W1) at the Chair for Dynamics, Control, Machine Learning and Numerics at FAU, Friedrich-Alexander-Universität Erlangen-Nürnberg since March 2021.
I am working on optimal control of partial differential equations and applied analysis in general.
I obtained both my Diploma (Oct 2011) and PhD (March 2017) in mathematics at TU Darmstadt, Germany; my PhD supervisor was Stefan Ulbrich.
I then moved to RICAM in Linz, Austria, for a PostDoc position in the “Optimization and Optimal Control” group of Karl Kunisch, in September 2017.

Research interests
My research interests concern problems at the intersection of (optimal) control and optimization with the analysis of PDEs.
This includes
• regularization aspects on the optimization side
• regularity theory for elliptic and parabolic evolution equations on the analysis side
The research questions I consider are motivated mostly by
• optimal control problems subject to strongly nonlinear (coupled systems of) time- dependent PDEs,
• real-world applications with nonsmooth data
Projects
• CIN-PDE: Control, inversion and numerics for Partial Differential Equations (2022 – 2025)
Awards
• Preis für hervorragende wissenschaftliche Leistungen (2018) TU Darmstadt
Award for outstanding scientific achievements for the best PhD dissertation at the Department of Mathematics at TU Darmstadt in 2017
