Current Research

Collaborative research in Antarctica, carried out jointly with members of the Structure, Tectonics, and Metamorphic Petrology (S.T.A.M.P.) group at University of Minnesota, focuses on the architecture and emplacement mechanisms for the Fosdick Mountains gneiss dome in West Antarctica. The project is part of a long-term research program exploring the geological evolution of Marie Byrd Land, the development of the Mesozoic West Antarctic rift system, and the tectonic processes that led to breakup of the active margin of the Gondwana supercontinent in Cretaceous time.
