Research interests

I am an ecologist and evolutionary biologist. My research focuses on phenotypic plasticity of animal behaviour and life history: how behavioural individualities emerge and how aging patterns are shaped in the face of perceived threats, and how dormancy aids dispersal. The main model organisms in my research are Daphnia, but other water fleas, rotifers, insects and frogs are included, too.
