I have trained as a biologist with a focus on mathematical modelling in evolution and ecology. Since my PhD, jointly at the Charles University, Prague and at the University of Edinburgh, I have focused on evolutionary genetics and evolutionary ecology. Since then, I have been developing fundamental theory of species’ connectivity and its limits, working both on theory of speciation and species’ range evolution. My research focuses on advancing theory to address fundamental questions in evolutionary ecology and specifically, on the evolution of species’ ranges in the light of environmental change. I employ both analytical and numerical treatments for models that combine population genetics with ecological dynamics. Recently, I provided the first testable predictions for a collapse of a species’ range, which arises from an intrinsic interplay between evolutionary and ecological dynamics. I have also described the phenomenon of dynamic range fragmentation, and secured research funding to study this interesting process in both static and changing environments. Lately, I have also contributed to epidemiological modelling of COVID-19.
