Research Group Profile
General interest areas
In my group we do mostly inorganic geochemistry focusing on chemical equilibria and transport phenomena in solid-Earth systems (and to some extent in other terrestrial planets and meteorites). This umbrella takes in a wide range of systems, spanning the realm from core-mantle interactions to climate proxies. We use mainly experimental approaches—coupled in some cases with numerical modeling—to characterize processes that operate in and on the Earth to redistribute the chemical elements on scales ranging from micrometers to kilometers. This overarching interest involves specific studies of several types, including: 1) partitioning of trace elements between minerals, silicate melts and fluids; 2) atomic and molecular diffusion in crystals, grain boundaries, silicate melts and supercritical water; 3) equilibrium and kinetic properties of low-abundance minerals that sequester geochemically-important isotopes and trace elements; 4) wetting behavior of fluids and melts in rocks; 5) permeability of (and bulk diffusion in) polyphase materials consisting of crystals and fluid; and 6) dissolution and growth kinetics of minerals, in particular as the latter might bear on non-equilibrium uptake of elements and isotopes. The primary application areas of current research include “environmental” conditions on earliest Earth (as these might bear on the origin of life), time-temperature evolution of igneous and metamorphic systems, and the underlying thermodynamic/kinetic basis of climate proxies.
