Welcome to my homepage!
Research
My research interests include the following topics:

- Discontinuous-Petrov-Galerkin-Methods (DPG)
- Parameter identifaction for linear wave equations - Full Waveform Inversion (FWI)
- Regularized inexact Newton methods
- The implementation of methods above for parallel exascale computers
- Relation of Machine Learning and Inverse Problems methodologies

Software
We developed a playground to experience acoustic waves in inhomogenuous media. Further, you can observe a simple FWI-algorithm at work.
