  • Summary Statement of Research Interests

    I am interested in the coevolution of the biosphere and the physical planet, which I look at through the lens of sedimentology, stable isotope geochemistry, and radionuclide geochemistry. I am currently working on whether the evolution of trees in the Devonian Period (~400 Ma) altered the sensitivity of terrestrial silicate weathering and caused a drawdown in atmospheric carbon dioxide. I am also investigating erosional fluxes during the Ice Age extinction (~13,500 years ago) in Southern California to better understand the drivers of this event, particularly the hypothesized role of humans.
