Research interests
I am interested in using geochemical tracers (trace metals, radiogenic and non-traditional stable isotopes) from deep-sea sediments and seawater to explore the relationships between global climate and ocean circulation, atmospheric circulation, marine biogeochemical cycling, continental aridity and hydrology over modern and recent Earth history (Quaternary). My recent and on-going research investigates:
- The dynamics of the intertropical convergent zone (ITCZ) over glacial-interglacial timescale
- Intermediate water circulation across abrupt cooling events during the last deglacial
- The biogeochemical cycing of Cd istopes in modern marine environment
- Marine barite cycling inferre from Ba isotopes
- Th-234 derived fluxes of organic matter and trace metals in the Peruvian Oxygen Minimum Zone
