I am interested in understanding long-term controls on the Earth’s terrestrial climate and oceans, particularly over the Cenozoic. During this interval, the Earth underwent a fundamental shift in its climate, transitioning from the hot, high-CO2 climate that characterized the Eocene to the relatively cool, low-CO2 climate of today. Understanding this transition can elucidate first-order controls on Earth’s climate as well as improve understanding of what our future climate may resemble given current projections of CO2 emissions.
My current projects include: 1) Reconstructing Central Asian climate over the past 80 million years using stable isotopes from paleosols; 2) Understanding the role of silicate weathering in modulating high CO2 and low CO2 climates; 3) Tracking changes in biomass production in North America using a compilation of paleosol carbonate stable isotopes; and 4) Reconstructing the ocean’s carbonate saturation state over the Cenozoic using a novel planktonic foram Sr/Ca proxy.
