Aqueous geochemistry and mineralogy

My research is in aqueous geochemistry and mineralogy. The long-term goal of my work is to develop a molecular-level understanding of the geochemical processes that couple the lithosphere, hydrosophere and biosphere. To this end, I use synchrotron-based spectroscopy and theoretical (quantum mechanical) calculations to explore the complexation of aqueous ions by dissolved ligands and mineral surfaces. These complexation reactions control the formation of ore deposits and fate of micronutrients, toxic heavy metals and radionuclides in the environment.

I am also exploring the electronic structures and crystal chemistry of iron and manganese oxide minerals as these minerals play a fundamental role in aqueous trace metal geochemistry and electron transfer processes in biogeochemical systems.
