Research Statement

As an organic geochemist, I work at the interface of biology, chemistry and geology and my overarching research interests revolve around the role of microorganisms in the regulation of global biogeochemical cycles. Understanding microbial transformations in the oceans is important for predicting future carbon sequestration and nutrient cycling. I am particularly interested in studying the ecophysiology of microbial communities in energy- and nutrient-limited environments, such as the open oligotrophic ocean and marine sediments. To this end, I investigate molecular-level responses of marine organisms to their changing environment, i.e. the information encoded in the molecular and isotopic composition of microbial membrane-forming lipids. By using the emerging field of lipidomics, I aim to contribute to our understanding of how and why organisms leave their particular chemical signals and to provide new insights on the microbial processes that drive biogeochemical processes in the modern ocean and the geological past.
