My research focuses on the mechanisms that govern climate variability on centennial and longer time scales. In particular, I am interested in quantitative reconstruction of the ocean circulation and the role the ocean circulation plays in the global cycles of water and carbon. We use the following analytical techniques: stable isotope geochemistry, trace and minor element geochemistry, and radiocarbon and U/Th geochronology.

Recent and ongoing research projects include

• The effect of sea level on mid-ocean ridge magmatism
• Holocene variability of the El Nino Southern Oscillation using stalagmites from Borneo
• Stable isotope tracer budget constraints on deep ocean mixing during the Last Glacial Maximum
• Reconstructing the radiocarbon content of the deep Pacific Ocean during the last deglaciation
• Exposure age dating of Holocene glacial moraines in the tropical Andes
• Gulf Stream temperature, salinity and transport during the last millennium
• Anthropogenic carbon dioxide uptake in the North Atlantic
