I am a field and metamorphic geologist with expertise in phase equilibria and the generation, segregation and migration of melt in the lithosphere. I am particularly interested in the geodynamics of the early Earth and the genesis and modification of Earth's first stable continental crust. I am increasingly dabbling in magma oceans and the metamorphism and anatexis of asteroids during the early evolution of the solar system, with implications for the formation of planets/planetesimals/moons.
