GEOLOGICAL SCIENCES AT BROWN UNIVERSITY
RESEARCH INTERESTS: My main research follows two related paths: first, early differentiation of the terrestrial planets with implications for the formation of mantle reservoirs and the enhancement or suppression of convection; and second, large-scale dynamic processes in the upper mantle and lithosphere that lead to magmatism. RESEARCH METHODS that I use integrate techniques from theoretical geophysics and igneous petrology. I use numerical fluid dynamic models (ConMan, CitCom, and others) and constraints from experiments (piston-cylinder and multi-anvil) and field petrology (occasional field trips combined with analyses of natural samples). We are also in the process of building a fluid tank to investigate processes of crystal settling in convecting magma oceans. Specific research topics have included melting in subduction zones as well as under continental lithosphere in the absence of subduction, magmatism as a result of giant meteorite impacts, and early planetary differentiation on the Earth, Moon, and Mars.
