ECOS
Department - 100 Morrissey Blvd. - Boston, MA 02125 My research examines the dispersal and fate of
contaminants in linked watershed and coastal environments,
biogeochemical and environmental tracers (radionuclides and stable
isotopes), and environmental remediation and management. Throughout
the world, human population growth and urbanization are driving
accelerated changes in environmental quality and ecosystem structure
and functioning at the land/ocean interface. The distribution of
radionuclides, stable isotopes, and other biogeochemical tracers
(identified in the illustration) can be used to study the complex
biological, chemical, physical, and geological interactions that
affect the transport, cycling, and ecological fate of materials in
terrestrial and aquatic systems. Natural and anthropogenic
radionuclides have an advantage over other types of biogeochemical
tracers because they not only serve as tracers to quantify the net
effect of complex biogeochemical interactions, but they also decay
with a constant half-life and serve as biogeochemical clocks to
quantify the rates for environmental and ecological processes. Although my research activities have focused on the
fate of radionuclides, carbon, and trace substances in river,
reservoir, estuarine, and coastal environments; I have also
conducted studies on the hydrological and biogeochemical processes
governing the movement of materials in watersheds. Specific research
activities involve determining: SGER: Exploratory Research on the Environmental Impact of
