My work focuses on understanding the evolution of earth's oceans and climate in the past. The deep sea houses one of earth's greatest archives of geologic history- layers and layers of mud that build up over time. I measure the chemistry of microfossils found in deep-sea sediments, called foraminifera, to reconstruct changes in ocean carbonate chemistry, such as CO2 content, through time. We also grow foraminifers in the laboratory in order to make calibrations for paleo-application.
My projects to date have included: calibration studies of the B/Ca proxy in living planktic foraminifers under simulated Paleocene seawater chemistry, and reconstruction of deep Atlantic carbonate chemistry in the last million years.
