# overview
My research focuses on metamorphic petrology and geochemistry; the characterization of metamorphism in the earth's crust and mantle including temperatures, pressures and, in particular, fluid compositions and movements.  This research includes fieldwork, petrography, microprobe analyses, fluid calculations over a wide range of pressures and temperatures, fluid inclusion work and stable isotopic analyses.  Recent research includes the production and microthermometric examination of synthetic fluid inclusions.  Additional interests include crustal genesis, Precambrian geology, economic geology, and metasomatic transport of crustal materials.
