My research focuses on the integration of textural, chemical, and in situ petrological and geochronological data sets to reconstruct physical conditions, timescales, and tempo of metamorphic processes. My projects are largely field-based, although I have a strong interest in utilizing modern computational tools (including Thermocalc, Perplex, and Theriak-Domino) to reconstruct the burial and exhumation histories of mountain belts. My research projects have ranged in timescale from the Archean, examining the old roots of mountain belts, to the modern U.S. Cordillera, looking at more recent mountain-building processes. Current field areas are in the northern panhandle of Idaho (Priest River and Clearwater complexes), the Bitterroot Range south of Missoula, and in the Precambrian Laramide uplifts of southwest Montana. I also have been the lead instructor and co-PI for a K-8 teacher professional development program in the physical sciences as part of the Big Sky Science Partnership (BSSP), an NSF-funded Math & Science Partnership program.
