Environmental Geochemistry Laboratory

The Environmental Geochemistry Laboratory supports the research activities of Dr. Schiff's graduate students and provides technical and analytical support to graduate students in the departments of Earth and Environmental Sciences, Geography & Environmental Studies and Biology. Students are encouraged to gain as much practical experience as possible in both field and laboratory geochemical techniques. Research technicians provide training and assist in the preparation and analysis of students' samples. Students also prepare isotope samples and participate in their analysis in the Environmental Isotope Laboratory. Technicians are also involved in the development of new analytical techniques as well as in the design and implementation of field projects. Staffing levels vary as a function of the type and size of projects being conducted within the research group.
