I am interested in the behavior of fluids in the Earth’s crust, especially water, carbon dioxide, and hydrocarbons.  My research is currently focused in three areas:  origin of hydrothermal carbonate-hosted base metal deposits, the porosity wave mechanism for anomalously rapid transport of fluids through low permeability geologic media, carbon dioxide sequestration in hydrocarbon reservoirs and saline aquifers.  My research combines:

• numerical modeling to simulate fluid flow, heat and solute transport, and chemical reaction
• analyses of fluid inclusions and minerals to determine fluid compositions and temperatures
• laboratory experiments to quantify the exchange of base metals between water and carbonate minerals
