John Berges

John Berges is Professor in Biological Sciences and Affiliate Professor at the School of Freshwater Sciences, University of Wisconsin-Milwaukee. His laboratory integrates physiological, genomic, and ecological approaches to study aquatic microorganisms across bacteria, phytoplankton, and fish.

Research examines stress responses in phytoplankton, ecological consequences of invasive species, and biogeochemical cycling in freshwater ecosystems. Recent work develops digital twins of plankton systems and climate impacts on decomposition. Publications demonstrate consistent focus on Great Lakes ecology (40%), microbial physiology (30%), and methodological innovation (30%).

Laboratory techniques span genomic analysis, biochemical assays, and field sampling. Collaborative projects investigate wastewater bioremediation and microbial fuel cells. No awards or specific student advisees are documented.
