Research

My research interests involve five main areas: (1) geochemistry of mineral surfaces and their reactivity with aqueous metal complexes, organic matter, and microbial organisms; (2) structure and properties of natural and manufactured nanoparticles; (3) environmental chemistry/geochemistry of heavy metal and actinide contaminants; (4) experimental studies of carbon sequestration through mineral carbonation reactions; and (5) structure-property relationships of silicate liquids and glasses. The first four areas have bearing on the sequestration, transport, and transformations of environmental contaminants (e.g., mercury, lead, arsenic, uranium, and CO₂) in aquatic systems, soils, and the atmosphere; the last focuses on the high-temperature geochemistry of silicate magmas and their trace elements. My students and I utilize various types of macroscopic and microscopic measurements, including the very intense x-rays from synchrotron radiation sources, as well as field investigations.

Teaching

I teach courses at both the undergraduate and graduate levels, including Earth Materials (GES 102), the basic sophomore-level course required of GES majors on minerals and rocks and the processes that form and modify them; Environmental Geochemistry (GES 170), a senior-, first-year graduate-level course on the chemistry of the environment; and Physics and Chemistry of Minerals and Mineral Surfaces (GES 261), a graduate-level course on my specialty. I also occasionally teach a sophomore seminar on environment and human health as well as graduate seminars on current topics in environmental geochemistry and mineral surface and aqueous geochemistry.
