I am a Columbia Science Fellow in the Department of Earth and Environmental Sciences at Columbia University. I teach Frontiers of Science, an interdisciplinary science course that is part of Columbia's Core Curriculum. I am also a Research Associate at the Lamont-Doherty Earth Observatory (LDEO).
My research interests involve the application of isotope geochemistry to Paleoceanography. An overarching theme of my research is how the “Global Conveyor Belt” or thermohaline circulation (THC) was different in the past. Many studies have focused on the deep arm of the THC, trying to assess changes in the strength of North Atlantic Deep Water (NADW) formation and its characteristic properties over glacial-interglacial and millennial timescales. My research focuses on the surface return flow of the THC.
