Mathematics graduate, Technical University of Munich
I studied Mathematics (BSc, minor in Computer Science) at the Technical University of Munich, with a semester abroad at Nanyang Technological University, Singapore. My bachelor's thesis, on explicit solvers for time integration with extended stability domains, was completed at the DLR Institute of Robotics and Mechatronics.
I'm currently working as a Data Science Intern in battery-based electricity trading at Entrix Energy, researching German electricity markets and developing trading strategies. Before that, I was a research intern at the DLR Institute of System Dynamics and Control Engineering and a database developer at Uscale GmbH. I'm supported by the German Academic Scholarship Foundation through the Max Weber Program.
Outside of work, I play tennis and soccer, tutor mathematics, and play the saxophone.

Explicit solvers for time integration with extended stability domains
Standard explicit time-integration schemes are pushed to impractically small step sizes by stability constraints in mildly stiff problems; this thesis proposes a technique to approximate a low-rank representation of the system's Jacobian from multiple time derivatives and their Krylov space, and explores its use in stabilising existing explicit methods.
