Short Biography

I joined the USGS, Branch of Regional Research (Reston) as a chemist in 1997 after working as a marine scientist for the University of Delaware, College of Marine Studies.  My research activities are associated with the study of inorganic environmental contaminants specifically trace elements in water, sediment and biological tissue.  My current projects include: an environmental assessment of As and Hg in Ukraine and potential human exposure, the effects of Zn in drinking water on learning and memory, Zn and other metals in roadway contaminants, and the uptake of trace and rare earth elements by plants.
