My main research interests evolve around the evolution of Earth’s climate over the last ~3 million years, with an emphasis on glacial/interglacial and deglacial timescales. I use geochemical analyses on marine sediment cores to reconstruct past nutrient availability, biological productivity, and sea-surface temperatures to gain insight into the coupling between the ocean and the atmosphere and their role in modulating atmospheric carbon dioxide concentrations. In particular, I have further developed a technique to measure the nitrogen isotope composition of organic matter preserved within siliceous microfossil shells (diatoms) to reconstruct nutrient cycling in the polar oceans.
