I am an igneous petrologist interested in the role magmatic processes play in driving plate tectonics, building mountains, forming of volcanic belts and their associated geologic hazards, and forming hydrothermal ore deposits.
My research is focused on the evolution of magmatic systems. I study extinct systems, using exposures to explore internal processes driving magma, analogous to the plumbing systems feeding active volcanoes. I combine field geology, geochronology, geochemistry, and petrology to constrain conditions of magmatic storage and differentiation that result in either eruption or pluton emplacement and help us understand the larger architecture of magmatic systems.

USGS Geochron: A database of USGS geochronological and thermochronological data
The U.S. Geological Survey (USGS) has developed an updated geochronology database (USGS Geochron) to include geochronology summary and analytical data created or funded by the USGS.
Geologic Framework of the Intermountain West
The Geologic Framework of the Intermountain West project was launched with the goal of producing a new digital geologic map database and 3D geologic model of a transect from the Rio Grande rift to the Basin and Range, based on a synthesis of existing geologic maps with new targeted new mapping, subsurface data, and other data sets. This database will integrate disparate map data, resolve...
Serving the U.S. Geological Survey’s geochronological data
Geochronological data provide essential information necessary for understanding the timing of geologic processes and events, as well as quantifying rates and timescales key to geologic mapping, mineral and energy resource and hazard assessments. The USGS’s National Geochronological Database (NGDB) contains over 30,000 radiometric ages, but no formal update has occurred in over 20 years. This proj
Cenozoic Landscape Evolution of the Southern Rocky Mountains
The Cenozoic Landscape Evolution of the Southern Rocky Mountains Project is a multi-year investigation funded by the National Cooperative Geologic Mapping Program. This project utilizes a combination of geologic mapping, geophysical surveys, basin modeling, and structural, neotectonic, geomorphic, volcanic, stratigraphic, and geochronologic studies to better understand the geologic landscape of...
