Fields of Study
Paleoceanography, paleoclimatology, and biogeochemical cycles

Statement

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 Niño 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
