Dormancy is an ubiquitous trait in microbial communities. It describes the ability of an organism to switch into a metabolically inactive and protected state, for example in response to environmental stress. Dormancy has important implications for the evolutionary, ecological and pathogenic character of microbial systems. This project derives and analyses new stochastic individual based models for the dynamics of dormancy-exhibiting biological systems.

We pursue two larger goals: On one hand, we aim to understand the influence of dormany on patterns of genetic diversity through the tools of population genetics, deriving as scaling limits from individual based models dual pairs of processes of diffusions and coalescents that incorporate feaures such as varying population size.
On the other hand we study  invasion, fixation and coexistence regimes withing the framework of adaptive dynamics, again, based on individual based models and there many particle limits.
