Fields of interest: 
Paleoclimatology, paleoceanography, isotope geochemistry

 My research goals focus on furthering our understanding of the climate system through the application of geochemical techniques and reconstruction of paleoclimatic records. Specifically, I am interested in glacial/interglacial tranistions in climate and the mechanisms that amplify insolation forcing. My current project focuses on reconstructing past movements of the Intertropical Convergence Zone (ITCZ) using 232Th, (231Pa/230Th)xs,0 and and 230Th normalized productivity proxies.  The goal of this project is to ground-truth hypotheses about the mechanisms moving CO2 to/from the deep ocean on glacial/interglacial timescales.
