Research Interests
Application of radiogenic isotope systematics to earth sciences.
Current Projects
My current projects involve investigations of the generation of basaltic magmas beneath continents, the formation of Earth's lower continental crust, the volcanic evolution of the western U.S., the population of an on-line igneous rock database (NAVDAT), and the development of high efficiency ion sources for thermal ionization mass spectrometry.
