My research interests center on phenotypic variation and species adaptation. By integrating genetic, behavioral, and environmental data I aim to understand both the proximate and ultimate causes driving traits to change over time.

My current work at Bielefeld University is nestled within the DFG-funded Collaborative Research Centre Transregio NC³ and aims to better understand the fitness consequences of niche choice and niche conformance. We use the Antarctic fur seal as a model system and employ genetic, behavioral, and time-series data to address these biological concepts.

During the first field season from November 2018 – April 2019, we aim to collect data from mother-offspring pairs in two neighboring colonies of high and low social density on Bird Island, South Georgia. By assessing individual quality and collecting data on immune response, hormonal response, gene expression, epigenetics, and movement patterns, we hope to better understand how an individual’s phenotype my interact with its environment.

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