Fields of interest: 
Paleoclimatology

I investigate global climate variability recorded in natural climate archives such as ocean sediments, corals, speleothems and tree rings. The main focus of my research is on the evolution and dynamics of the El Nino-Southern Oscillation in the Pacific Ocean, and on tropical-extratropical climate links over glacial cycles in Earth's past.
