Department of Geology and Geophysics


My research interests encompass the fields of biogeochemistry, paleoceanography, and paleoclimatology, with a focus on understanding the factors driving climate during the Cenozoic era.  My approach applies the isotopic compositions and abundances of organic molecules (biomarkers), and records of stable isotope- and trace-element compositions of species-specific foraminifera to constrain the physical and environmental conditions of ancient oceans, terrestrial systems, and the atmosphere.


Research Topics

Our group is involved in a wide variety of projects that span short- and long timescales, including: 


• The Cenozoic evolution of atmospheric carbon dioxide 

• The character of carbon input during the Paleocene-Eocene thermal maximum

• Arctic hydrology during the Paleocene-Eocene thermal maximum

• The long-term history of C4 photosynthesis

•Limate and the end of the Classic Mayae

• Carbon and hydrogen isotope compositions of modern leaf wax lipids

• Pliocene CO2 and temperature
