Research interests
We analytically and numerically investigate nonequilibrium systems that involve noise and time delays. In particular
- Analytical treatment of stochastic delay differential equations
- Fokker-Planck equations for systems with memory
- Stochastic Thermodynamics of non-Markovian and active systems
- Delayed feedback control
