Research Summary

My research over the past 35 years has emphasized the effects of nutrient over-enrichment, related pollutants, and changing nutrient stoichiometry on aquatic ecosystems spanning from freshwaters to estuaries and marine coasts.  I especially have focused on harmful algae such as toxigenic cyanobacteria and dinoflagellates, and on beneficial seagrasses. I have also studied chronic effects of eutrophication on higher trophic levels such as finfish and shellfish.  My most recent work has been in Falls Lake, a major potable water supply reservoir in the North Carolina Piedmont.
