Research focuses on igneous and metamorphic rocks, and the interpretations of earth processes
relevant to mantle and crustal evolution and stability. Recent research includes:
Modification of Archean Age Cratons by Flood Basalts in Southern Africa
Subduction plate internal structure imaged through seismology and mineral constraints
Investigations into the initiation of rifting in the Gulf of California
Investigation of mountain-building events in the New England segment of the Appalachians.
Study of the dynamics of large-scale magma chambers, such as those of the Sierra Nevada.
Investigating the role of magma-mixing in the formation of granites.
Use of trace elements to characterize orogenic vs. anorogenic tectonic regimes.
Investigation of the metamorphism of carbonaceous materials.
