Research interests

  • I am interested in transport and condensation phenomena occurring in nonequilibrium jump processes. These processes find a broad range of application, for example in the study of
    • mass transport models (condensation and depletion of network nodes / lattice sites),
    • condensation in nonequilibrium boson systems that are incoherently driven and dissipative (condensation and depletion of quantum states),
    • evolutionary game theory (win and loss of strategies)
    • biodiversity in population dynamics (survival and extinction of species), and
    • in autocatalytic bimolecular reaction networks (production and consumption of chemical species).
  • From a mathematical point of view, I study the interplay between nonlinear dynamics (arising through particle interactions or quantum statistics) and stochasticity (arising through demographic noise). This interplay gives rise to interesting phenomena ranging from transport to condensation of particles.
  • Furthermore, I am interested in the evolution of cooperation at microbial level (public goods dilemma) and, more generally, in microbiology.
