Research Interests


Theoretical and experimental studies of the thermodynamics, kinetics and molecular mechanisms of aqueous processes and water-rock interactions, especially at elevated temperatures and pressures. Particular emphasis on metals and their speciation and transport. Solubility, calorimetric, spectroscopic, electrochemical, phase equilibrium and other experimental studies. Field-based studies of ore deposits, geothermal systems and the environment. Equilibrium and reaction-path modeling of geochemical processes. Applications to ore deposits, hydrometallurgy, exploration geochemistry, environmental geochemistry, radioactive waste disposal and medical geology. Particular interest in rare earth (REE) and platinum group elements (PGE).
