Field, laboratory, and theoretical studies of tectonics, particularly: i) the formation and exhumation of ultrahigh-pressure rocks; ii) ophiolite emplacement and the formation of inverted metamorphic gradients; iii) the role of phase changes in earthquakes, diagenesis, and magmatism in subduction zones; iv) the formation and refining of continental crust; v) rheology, anisotropy and phase changes in the lower crust; and vi) rock physical properties. Analytical method development: electron back-scatter diffraction (EBSD), laser ablation split stream inductively coupled plasma mass spectrometry (LASS), monazite and titanite chronometry. Software development: 40Ar/39Ar data analysis, ICP data analysis, rock physical properties.
