I am a geochemist interested in the broad processes occurring within and between the Earth鈥檚 crust, mantle, and surface. An interest in unraveling the history of the Earth, as well as predicting certain aspects of its future, is at the heart of much of the research going on in my group. By studying the vast geological record, we interpret the chemistry of diverse Earth materials (rocks, minerals, sediments, and more) to elucidate the timescales, rates, and mechanisms of broad and interdependent geological processes such as听tectonics, metamorphism, subduction, global geochemical cycles, lithosphere-hydrosphere-atmosphere interactions.听听My research brings together approaches including听isotope geochemistry, geochronology, field geology, petrology & mineralogy, thermodynamics, and numerical modeling.听My research has taken my students and me to field areas including Austria, Italy, Spain, Switzerland, Scotland, the Greek Isles, China, Ontario, California, and throughout New England.
