Interests in igneous and metamorphic petrology, structural geology, and Appalachian tectonics

My Ph.D. research focused on the construction and evolution of shallow granitic plutons in the upper crust and the generation of granitic partial melt in the deep crust. Active field research is centered on the Schoodic Peninsula in eastern coastal Maine and the Fehr granite in the Athabasca Granulite Terrane in northern Saskatchewan . Multiple analytical techniques are being employed to better understand the generation and transport or partial melt and emplacement of granitic plutons. Avenues currently being explored include: qualitative textural studies using traditional petrographic techniques as well as mapping with a Cameca SX50 electron microprobe, quantitative approaches include whole rock major and trace element geochemistry via XRF and ICP-MS, TIMS whole rock isotope studies, micro-drilled plagioclase single crystal isotope geochemistry, hornblende barometry, single crystal microgeochemical analyses of major phases, and FTIR studies of plagioclase, quartz, and hornblende devitrified and non-devitrified melt inclusions.

My current research with the Office of the Massachusetts State Geologist is funded by the Department of Energy Geothermal Research Initiative and focuses on better understanding the geothermal potential of granitoids in Massachusetts and Connecticut.
