Research Interests:

Our work has traditionally focused on enumeration and the physiological performance of phototrophs and ecologically important chemolithotrophs in aquatic systems. Specifically, we currently examine the composition and dynamics of cyanobacterial and microbial communities in freshwater environments, focusing primarily on the N and P cycles in the Laurentian Great Lakes. These studies have assisted in the assessment of factors contributing to toxic cyanobacterial bloom events in regional lakes. BGSU's efforts examining cyanobacterial blooms have led to the formation of the NIEHS and NSF-funded Great Lakes Center for Freshwaters and Human Health (PI Bullerjahn).
