Education

Ph.D. Geology: University of Minnesota–Twin Cities, 2009
Thesis title: “Melt transport and magma accumulation in a migmatite-cored gneiss dome, Fosdick Mountains, West Antarctica”
Advisors: Christian Teyssier, Donna L. Whitney

M.S. Geology: University of Wyoming, 2004

B.S. Geology-Biology: University of Rochester, 2001

Research 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; Klamath Mountains, California

Current research

My current research is on the evolution of the isthmus of Panamá. I am conducting field-based structural geology and geochronology to study an arc-related plutonic complex in Eastern Panamá.
