My main area of research has focused on heavy metals exposure and effect. The current emphasis is on the relationship between mercury and selenium exposure and balancing the risks against benefits of fish consumption. Much of this work involves Native American and Alaskan Native communities. A second area focuses on the environmental consequences of energy options, examining nuclear options in the light of the spent nuclear fuel impasse and the Fukushima disaster vs unintended consequences of renewable energy. This has been developed as an outgrowth of our CRESP work on hazardous waste, risk management, and land use decisions with the U.S. Department of Energy. A third area focuses on incorporating workplace health and safety equity into the EPA’s “Environmental Justice” paradigm.
