About Me

I am an Assistant Professor in the Department of Geology and Geophysics at Texas A&M University, and an isotope geochemist and stratigrapher who studies how Earth’s surface environments have responded to major changes throughout deep time. My research focuses on extracting geochemical signals preserved in marine sedimentary rocks using radiogenic Re–Os isotopes and non-traditional stable isotopes, including Ca, Sr, Cr, and Fe, to reconstruct past biogeochemical conditions associated with the emplacement of large igneous provinces and other major Earth-system perturbations recorded in the sedimentary archive.

I also use platinum group element geochemistry— Os, Ir, Ru, Rh, Pt, and Pd to fingerprint magmatic sources and to quantify the magnitude and environmental influence of volcanic and extraterrestrial inputs to the Earth system. These approaches allow me to directly link sedimentary records to volcanic, tectonic, and climatic drivers of change.

I integrate these proxy records with numerical box models to investigate the processes that drive global biogeochemical change, bridging local sedimentary observations with Earth-system–scale dynamics. My work spans much of geologic time, from the Ediacaran to the Holocene, and includes studies of Mesozoic ocean anoxic events, the Devonian–Mississippian interval, the Paleocene–Eocene Thermal Maximum, the K–Pg boundary, the Miocene Climatic Optimum, the Younger Dryas, and modern sediments.

Opportunity

I am actively seeking motivated postdoctoral researchers and graduate students to join my research group. Prospective students interested in the Texas A&M University Geology and Geophysics graduate program are encouraged to visit the department’s graduate program webpage for additional information. For prospective graduate student and postdocs, please contact me with a copy of your CV and provide me with a little bit more detail about yourself and what you are interested in working on. I also encourage current Texas A&M geology or chemistry undergraduate students to contact me directly to discuss potential research opportunities.
