I am a geochemist interested in the broad processes occurring within and between the Earth’s 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 asÌýtectonics, metamorphism, subduction, global geochemical cycles, lithosphere-hydrosphere-atmosphere interactions.ÌýÌýMy research brings together approaches includingÌýisotope geochemistry, geochronology, field geology, petrology & mineralogy, thermodynamics, and numerical modeling.ÌýMy 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.
