- Metamorphic Petrology
- Convergent Margin Tectonics
My research addresses questions about geochemical and tectonic processes at convergent margins, including the timing and rates of subduction, exhumation, and associated metamorphism, the deformation and rheological behavior of the subducted oceanic crust and sediments, and the nature and effects of fluid-rock interaction. I use a wide range of methods to address these questions, including field-based studies of exhumed subduction complexes, geothermobarometry, geochronology, and other micro-analytical techniques (EMPA, EBSD, LA-ICPMS).
