I study how Earth's climate and the ocean system have changed over time, from Cenozoic warm periods to glacial–interglacial cycles. My research focuses on reconstructing past biogeochemical cycles, spanning large-scale processes like oxygen minimum zones, productivity, and nutrient dynamics, down to finer-scale interactions of nutrient recycling and symbiosis in foraminifera (my favourite sidekick in my research!). I use a mix of geochemical tools, including lipid biomarkers and fossil-bound nitrogen and carbon isotopes, to piece together how greenhouse gases, ocean circulation, nutrient cycling, and tectonics have shaped the Earth system.
