Research Interests

My research group works on problems related to igneous petrology and tectonics. Much of our research is driven by field observation coupled with geochemical measurements that are made back in the laboratory. Our primary analytical tool is U-Pb geochronology by thermal ionization mass spectrometry, which provides high precision age constraints for ancient rocks. Current projects include the evolution of fossil subvolcanic magma reservoirs in Nevada and reconstructing the tectonic evolution of the Pacific Northwest.
