Research interests

  • History of the deep ocean circulation
  • Evolution of African and South American climates
  • Climate of the last 150 ka, in particular of the Last Interglacial
  • Tracers: foraminifera (stable isotopes, trace elements), inorganic geochemistry (XRF), organic geochemistry
  • Model-data comparison

Current research

  • Evolution of South American and tropical Atlantic climate across the Last Interglacial (EndLIG project).

Projects

Ongoing projects

Past4Future: This European project investigates the climate and environment of past warm periods (interglacials) to inform on future climate and possible abrupt changes.
