Research Interests

In my research, I was so far concerned with the data-driven construction of reduced simulation models. The following methods were used for this purpose:

• Physics-Informed Neural Networks (PINNs)
• Reinforcement Learning

The methods were applied for shape optimization of flow channels in profile extruders as well as for the prediction of flow fields in bioreactors.

Academic Career

I started studying Computational Engineering Science at RWTH Aachen University in October 2014. In my bachelor's degree, I broadened my knowledge in energy technology with a focus on renewable energies. After my bachelor, I continued my studies with a master in the same subject, but then focused on numerical methods for fluid dynamics simulations.

Starting in March 2020, I did my PhD as part of the HDS-LEE Graduate School, which deepened my knowledge about machine learning.
