Research Interests

I am currently in my second PhD year at the University of Heidelberg. As a member and scholarship holder of the Heidelberg Graduate School of Mathematical and Computational Methods for the Sciences, I am working on the "Optimization of Coupled Supply-Demand-Price Networks in the Chemical Industry" with a mathematical focus on global optimal control.

My scientific interests include the solution of nonlinear mixed-integer optimal control with direct methods, in particular multiple shooting. Depending on the application, many extensions such as nonlinear model predictive control are necessary. In this context, I also worked on the real-time application of our mathematical methods.

My research at the Interdisciplinary Center for Scientific Computing (IWR) allows an application driven, interdisciplinary approach to new mathematical challenges. During my education, I worked extensively on several applications, including models from economics, psychology and robotics.
