My research uses a stratigraphic approach to combine detailed fieldwork with the acquisition of high-precision U-Pb zircon geochronology, geochemical, and paleomagnetic data to work towards answering a variety of Earth history questions in paleoclimatology, volcanism, and tectonics. I am particularly interested in using geochronology to investigate the role large igneous provinces may play in perturbing the Earth system, and to calibrate the Geologic Time Scale during critical intervals of environmental change. During my PhD, I obtained the first U-Pb eruptive timeline for the Columbia River Basalt Group (CRBG), which has been suggested to be the primary driver of the roughly concurrent Miocene Climate Optimum (MCO). As an NSF Postdoctoral Fellow, I am currently investigating the connection between Miocene volcanism and climate change by generating a high-resolution foraminiferal boron isotope-derived pCO2 proxy record from ODP Site 1000, calibrated by a novel integration of high-precision zircon geochronology obtained from ashes in the same core.
