My research interests have been in the area of applied aquatic microbiology and limnology including eutrophication, biological wastewater treatment, biological phosphorus removal, and whole effluent toxicity.  My laboratory is now closed.  I have no current students and will not be taking new students.

I just completed an investigation of the causes of low dissolved oxygen concentrations below the lock and dams on the Middle Cape Fear River. In addition, I just completed an investigation of the factors that encourage re-growth of bacteria in drinking water distribution systems with Francis A. DiGiano.
