  • Summary Statement of Research Interests

    I am most interested in how large organisms (eg., plants, mammals, etc) change geomorphology, biogeochemical cycles, and climate (I term this Geo-Macrobiology) 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 (using Lithium isotopes) and caused a drawdown in atmospheric carbon dioxide.

    I am also working to understand how the arrival of humans have affected soil erosion rates (using cosmogenic nuclides) in the Channel Islands of California, starting from the first humans on the island (Ancestral Chumash ~13,500 BP) to the arrival of ranchers and herder on the island (~1800 AD) to the present. This work will help objectively quantify the effects that the overutilization of resources has had in two distinct periods in archaeological history.
