Research interests:

My research interests lie in the field of evolutionary ecology – how genes and environment interact in shaping life history and behaviour, in particular. I have focused on evolution and phenotypic plasticity of longevity, and studied also dispersal mechanisms in aquatic animals. I am now venturing into the study of how consistent between individual differences in behaviour, so called animal personalities, emerge. I am also interested in links between molecular, individual, population and community level responses to environmental change.
