about me
I am a PhD student at the Institute for theoretical physics, TU Berlin, in the group of Sabine Klapp. I am interested in analytical descriptions of non-Markovian systems, in particular, how the concepts of statistical mechanics can be generalized towards non-equilibrium systems with memory. I am especially interested in possibilities to describe stochastic systems with discrete or distributed time delay by means of stochastic thermodynamics. A suitable model is a Brownian particles subject to continuous feedback control. Some keywords:
- Stochastic delay differential equations
- Fokker-Planck equation for systems with memory
- Stochastic thermodynamics
- Nonlinear dynamics
final thesis
- Master Thesis | Noise effects on chimera states in the Stuart-Landau model
- Prof. Dr. Eckehard Schöll, at TU Berlin, March 2015
- Bachelor Thesis | Dynamik von Kolloiden in periodischen, zeitabhängigen Potentialen
- Prof. Dr. Sabine Klapp, at TU Berlin, September 2012

If I don't do physics, I also like climbing, trekking, traveling, cooking, arts, literature.
