Russell L. Cuhel, Senior Scientist, was born in Hollywood and raised in the City of the Stars. In college, he had already gathered over 150 days at sea, mostly in Antarctica, and 6 publications before he finished his Bachelor’s degrees in Biology and Chemistry at the UC San Diego (1975). As a graduate student in Marine Microbiology at the Massachusetts Institute of Technology and Woods Hole Oceanographic Institution (1975-1981), he studied extreme environments, which continues as a passion to this day. Research work at the Rosenstiel School of Marine and Atmospheric Sciences (U. Miami 1981-1989) added hundreds more days at sea covering most of the world’s oceans and a year-long time series on Lake Ontario. Adept at bench research, he began to include research education (high school to graduate student levels) as a major, well-integrated component of his service to UWM beginning in 1990. Building on a program initiated by Nealson and others, he brought the only freshwater Oceanography site of the National Science Foundation’s Research Experience for Undergraduates to national recognition.  Innovative integration of the REU education program and NSF-funded research on Yellowstone Lake hydrothermal vents allowed students to work side by side with active scientists in cross-cutting and environmentally relevant disciplines (geochemistry, geology, chemistry, microbiology, policy, engineering). Such Interdisciplinary Approaches are also the core of his diverse funded research programs, which include year-round sampling in Lake Michigan, Wisconsin Inland Lakes, Yellowstone Lake, and several marine sites including the Guaymas Basin hydrothermal system. Community outreach is also a critical component of UWM’s mission, and Cuhel and Aguilar are reliably present as educators at a variety of community functions.  Peer review of proposals and manuscripts, panel participation at funding agencies, and chairing of annual undergraduate research poster sessions at national meetings provides a taste of widely-recognized national service, all undertaken in the name of the University of Wisconsin-Milwaukee WATER Institute and now School of Freshwater Sciences.

Research Interests

  • Algae and bacteria: productivity and nutrient cycling, weather effects on lake and ocean plankton, nutrient limitation and eutrophication, seasonal cycles of plankton dynamics, episodic events influencing lake processes. Production of acid rain. Long-term studies of lake microbiogeochemical ecophysiology.
  • Invasive species. Zebra and Quagga mussels: effects on inland lakes and Lake Michigan; mussel feeding and effects on plankton composition; biochemistry of mussel tissue; basin-scale alterations in food web structure, optical properties, and seasonality.
  • Hydrothermal vents: microbiology and geochemistry of Yellowstone Lake hydrothermal vents; chemistry and microbiology of marine hydrothermal vents; growth of warm- and hot-environment bacteria.
  • Science education: Bench research education at independent study, student hourly, and capstone event levels; Career paths in environmental sciences; internships for students in aquatic sciences
