The new team members offer their expertise in using mathematical tools appropriate in dynamic biological systems analysis. Petr Chvosta applies methods used in stochastic thermodynamics and non-equilibrium energy conversion, Eva Pokojská focuses modeling and time-delay systems analysis.

Research perspective:
Our working hypothesis is that the spectrum of biological regulatory motifs that are responsible for emergent dynamic behavior is limited and is shared by various biological systems. We choose photosynthesis as the primary model system that is experimentally well accessible, and dynamically characterized. We continue the research of photosynthetic regulation by construction model networks that will be tested for analogies in other simple and complex systems. Description levels will range from molecular/cellular to individual/ populational interactions.
