Bio
I study fluid flow, chemical reactions, mass transfer, and heat transfer in Earth’s crust and upper mantle, with a focus on the metamorphic and igneous rocks comprising the deep roots of mountain belts. Our research group integrates fieldwork, chemical and isotopic analyses of rocks and minerals, and numerical simulations. Example research areas include heat and mass transport by fluid flow through porous and fractured rock; timescales of orogenic events; fluids and arc volcanism; the impact of subsurface fluids on rock rheology and earthquake hazards; geohydrology; the genesis of economic mineral deposits; processes that release and transport greenhouse gases such as carbon dioxide in Earth’s crust; and carbon sequestration. Field experience spans localities across the globe including British Columbia, California, Greece, Italy, Namibia, New England, New Zealand, Norway, Papua New Guinea, Scotland, South Africa, Spitzbergen, and Washington State.
Current Research
- Timescales of dynamic events (e.g., earthquakes, magmatism) preserved in the metamorphic rock record.
- Deep carbon, sulfur, redox, and hydrogen cycling in orogenic belts and subduction zones.
- REE and critical minerals cycling in metamorphic terranes.
- Genesis of ultrahigh-temperature and ultrahigh-pressure metamorphic rocks in extreme geologic environments.
- Regional metamorphic evolution of New England (USA).
- Theoretical modeling of heat and fluid transport in lithospheric systems.
- Current field areas include New England, Norway, and Scotland.
