Research

My research interests involve understanding how the continents of Earth have grown and changed through time. To address this question, I study metamorphic rocks from different places and times in Earth's history using fieldwork, petrography, radiometric dating, and phase-equilibria modeling. How/when did the rocks form and how/when were they brought to the surface? Are these processes the same today as they were in the past and if not, how are they different? How do these processes at depth influence what happens on the Earth's surface?

 

My current projects include studying the ultrahigh-temperature rocks of southern Madagascar (East African Orogeny, ~650-500 Ma) and the ultrahigh-pressure rocks from the Western Gneiss Region, Norway (Caledonian Orogeny, ~450-390 Ma).
