Professional Interests

I am interested in theevolution of orogenic crust, from the construction of crust in arc systems, tothe cooling and exhumation of middle to lower crust during extension. I amespecially interested in the influence of oblique tectonics on orogenicprocesses. My research emphasizes field-based structural geology andgeochronology (U-Pb, 40Ar/39Ar). Research projectsinclude: 1) Role of oblique tectonics in the emplacement of partially moltencrust, 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: Croydon Dome, NH; Panamá; Fosdick Mountains, West Antarctica;  Pioneer Mountains, Idaho; Klamath Mountains, California
