Research Interests:  Geochemical cycling of trace elements in natural and perturbed environments, particularly redox-sensitive processes affecting metals and metalloids.  Applications to mine tailings, coastal sediment, estuaries, and groundwater, as well reconstructions of past climate change in nearshore environments. Interest in the bridging of disciplines, including the health and social sciences, to address multi-faceted environmental problems.
