I am an evolutionary ecologist. My goal is to understand how trait changes and trait variation affect community structure and functioning of ecosystems in time and space. My main research interest focuses on the quantification of absolute and relative contributions of ecological and evolutionary processes and how these shape communities and metacommunities in their response to environmental change. In my daily research activities, I combine the development of conceptual and methodological frameworks and building theoretical models with experimental approaches using microcosm experiments to test theory.
