I study tectonics and climate using stable isotope biogeochemistry. Some of my projects include: 1. Examining the topographic history of the North American Cordillera using stable isotope paleoaltimetry; 2. Studying changes in the hydrologic cycle during hot, high-CO2 times in Cenozoic western North America. 3. Determining the effects of grasslands and other vegetation on climate through modeling and stable isotope paleoclimatology.
