The aim of my current work is to determine the fitness consequences of niche choice and conformance in the Antarctic fur seal using genetic, behavioral, and time-series data from mother-offspring pairs in two neighboring colonies of high and low social density.

At the University of Potsdam, where I completed my PhD work, I conducted research on the genetic and evolutionary basis of trait diversification in African weakly electric fish. This included research into gene expression, animal behavior, and genomics. Prior to that, I focused on the genetic and phenotypic effects of translocation events in red deer populations in southern Germany at the University of Mainz.
