Alexandra Auderset
Alexandra Auderset is a paleoceanographer and currently an Anniversary Fellow at the University of Southampton. She earned her PhD in 2020 through a joint program between ETH Zurich and the Max Planck Institute for Chemistry, followed by a Swiss National Science Foundation-funded postdoctoral fellowship at Princeton University. Her research focuses on reconstructing past climates, particularly Cenozoic warm periods and the Miocene. Using lipid biomarkers and fossil-bound nitrogen isotopes, she investigates biogeochemical cycling at multiple scales—ranging from ocean oxygen minimum zones to nitrogen recycling in planktic foraminifera. She is actively involved in PAGES working groups PO2 and MioOcean (part of PlioMioVAR), which explore past ocean oxygenation and Miocene temperature dynamics. Looking ahead, her research aims to refine our understanding on how nutrient dynamics influence ocean (de)oxygenation and their broader connections to the global carbon cycle and climate.
