Professional Interests

I am interested in the evolution of orogenic crust, from the construction of crust in arc systems, to the cooling and exhumation of middle to lower crust during extension. I am especially interested in the influence of oblique tectonics on orogenic processes. My research emphasizes field-based structural geology and geochronology (U-Pb, 40Ar/39Ar). Research projects include: 1) Role of oblique tectonics in the emplacement of partially molten crust, represented by migmatites, during orogenic evolution, 2) processes and duration of melt-present deformation in the middle to lower crust, 3) crustal growth during regional contraction and intracontinental extension, concentrating on pluton emplacement processes and petrogenesis. Field areas include: Panamá; Fosdick Mountains, West Antarctica;  Pioneer Mountains, Idaho; Klamath Mountains, California
