My research is directed towards understanding geochemistry related to radioactive waste disposal, environmental restoration, and climate change. My research has focused on coupling laboratory or field studies with state-of-the-art analytical techniques and/or geochemical modeling to determine important rock-water interactions that control water composition and the eventual transport of contaminants. My current focus is on the role that geochemical reactions play in geological sequestration of carbon dioxide.
