  1. Fluid-rock interaction -- Use light and heavy stable isotopes to trace element cycling between the Earth’s crust, the hydrosphere, and biosphere. Apply in situ analytical techniques to study tectonics, the timing of basin fluid migration in sedimentary environments, base-metal deposits, and the geochronology of uranium deposits and natural fission reactors. Study actinide migration in near surface environments and the kinetics of light stable isotope exchange in minerals.
  2. Nanoscience -- Couple nano- and micro-scale analyses to nanostructures in engineered and natural materials to characterize fluid-solid interfaces.
  3. Biogeoscience -- Study bacterial reduction of heavy metals, characterize nanoscale bio-precipitated minerals using SIMS and HRTEM techniques, and predict the stability of these phases based on their structure and thermodynamic modeling.
  4. Archaeometry -- The application of isotopic tracers in archaeological studies. For example using stable isotopes to identify and track Mesoamerican turquoise trade routes.
