My research interests range from the eruptive history of volcanic fields to the crystallization of individual phenocrysts to the interactions of mafic and felsic liquids in magma chambers. I study the geochemical, geochronological, and physical aspects of continental magmatic systems.  The research is field based, with supporting analytical tools including electron-microprobe analysis, 40Ar/39Ar geochronology, geochemistry, and GIS.  My current field areas include western Mexico and coastal Maine.

Current Student Projects
I am looking for students interested in pursuing field-based studies of eruptive deposits in western Mexico. We will spend ~10 days in the field characterizing, mapping, and sampling the ~200 ka tephra deposits from Volcan Tepetiltic. We will use GIS to help create isopach maps and assess the risks of future eruptions. Back on campus, we will use the scanning electron microscope and ICP-MS to determine the geochemical evolution of the tephra deposits.
