about me

I am a postdoctoral fellow with Marie-Skłodowska-Curie scholarship working at DAMTP, University of Cambridge, UK in the group of Mike Cates. I am also a Research Fellow of the Corpus Christi College, Cambridge. Before coming to Cambridge, I was at ICTP in Trieste in the group of Édgar Roldán, and at Leipzig University in the group of Klaus Kroy. In March 2020, I defended my doctoral thesis under the supervision of Sabine Klapp at TU Berlin. I am interested in how the concepts of statistical physics can be generalized towards non-equilibrium systems. Some keywords:

  • Stochastic thermodynamics

  • Non-Markovian, nonequilibrium processes

  • Control and Information theory

  • Nonreciprocal systems

  • Nonlinear dynamics

  • Nonequilibrium phase transitions

If I don't do physics, I also like climbing, being in the nature, arts, literature.
