Interactions of microbes with chemicals (nutrients, toxic substances) in the water column of lakes and rivers and the use of advanced technologies for assessing phytoplankton community structure and health as well as algal-derived biofuel production. Studies focus on the Laurentian Great Lakes and St. Lawrence River ecosystems, and involve work on both research vessels and in the laboratory using organisms isolated from these environments. This research is at the interface between microbial plankton ecology and analytical chemistry.
