Domain geoscience research interests: subduction and collision, from a geochemical/petrological perspective; studies of the petrogenesis and geochemical cycles of subduction channels, past and present, and the phenomena of subduction initation. Testing models for subduction recycling on a range of scales. Geochemical systematics of "fluid-mobile" elements and isotopic systems.
Geoscience Education interests: undergraduate research in courses and curricula; models for sustainable geoscience CUREs. Impacts of the classroom use of research instrumentation in geoscience courses. "Big" geo-data applications in courses, using Google Earth and like native GIS tools. Examining the educational impact of video animations of deep-earth processes on introductory and upper level students. Avant-garde strategies for dissemination of educational practices and resources. And helping establish community consensus on undergraduate and graduate geoscience curricula.
