Researcher Profile:

Dr. Casey Godwin recently joined CIGLR as an Assistant Research Scientist. He has a Ph.D. in ecology, evolution, and behavior from the University of Minnesota. His research focuses on how the elemental requirements of bacteria and algae couple carbon and nutrient cycles in freshwater ecosystems. The driving question behind this work is “as we continue to pollute our aquatic ecosystems with excess nutrients, will cycling of carbon and other elements change in proportion, or will fertilization decouple key ecosystem processes?” He has examined this question in the context of impact of stream algae on nutrient retention within watersheds, functional diversity of freshwater bacteria in response to land use change, and most recently, minimizing the fertilizer demand of renewable fuels produced from algae. As part of CIGLR, he is working on projects including the effects of nutrient abundance and forms on harmful algal blooms and the influence of hypoxia on the biogeochemical cycling of nutrients and heavy metals in Lake Erie.

Where others see muck, University of Michigan biologists, ecologists and engineers see a potentially renewable source of biofuel in algae. They’re working to reduce engine emissions and shrink carbon footprints by refining an algal diesel fuel that works just as efficiently as its petroleum-based counterpart.

University of Michigan scientists grew various combinations of freshwater algal species in 80 artificial ponds at U-M’s E.S. George Reserve near Pinckney, Michigan in the first large-scale, controlled experiment to test the widely held idea that biodiversity can improve the performance of algal biofuel systems in the field.
