Research

I study the physical and chemical processes of crustal deformation, particularly of the ductile-plastic lower crust, with an eye toward unraveling the tectonics of convergent and collisional margins. My first-year project at UCSB is lutetium-hafnium (Lu-Hf) dating of eclogites from the Western Gneiss Region (WGR) of Norway, aimed at more tightly constraining the timing of UHP metamorphism. My potential PhD projects include investigations of lower-crustal rocks in the WGR or the Himalayas (Tso Morari).

 

I am also interested in the thermodynamics of metamorphic systems, disequilibrium processes, geo- and thermochronology, strain localization, structural evolution of faults and shear zones, experimental petrology of Earth materials, and various topics in  planetary science (for example, impact cratering and lunar geology).
