Aqueous Biogeochemistry Laboratory

The Aqueous Biogeochemistry Laboratory is housed in Haenicke Hall, a modern facility built in 1997 integrating geoscience, biology and chemistry research laboratories  to promote active cross-disciplinary research and collaboration. The lab is supervised by Dr. Carla Koretsky, professor of aqueous geochemistry and biochemistry in the Department of Geosciences at Western Michigan University.
