My research is focused on the evolution of volcanic and plutonic systems, phenocryst crystallization, and the weathering of volcanic terrains. I study the geochemical, geochronological, and physical aspects of continental magmatic systems at a variety of scales, from volcanic fields to individual phenocrysts. I am interested in how volcanic systems change over time and how that history is recorded in individual phenocrysts. I am also interested in how volcanic rocks break down and weather and their contribution to soil and watershed chemistry. My research is field based and uses a variety of analytical tools, including ICP-MS, EMPA, SEM, GIS, and 40Ar/39Ar geochronology
