About
Dr. Gregory Dick is the Director of the Cooperative Institute of Great Lakes Research (CIGLR) and an Alfred F. Thurnau Professor in the School for Environment and Sustainability and the Department of Earth and Environmental Sciences. He also holds affiliations in the Department of Ecology and Evolutionary Biology, the Center for Computational Medicine and Bioinformatics, and the Chemical Biology Graduate Program. Professor Dick's research focuses on the role of microorganisms in shaping environmental processes, water quality, and biogeochemistry. His lab specializes in the use of 'omics (genomics, transcriptomics, etc.) to study microbial communities in a wide variety of environments including the deep sea, the Great Lakes, the human gut, and engineered systems. His current research focuses on the microbial ecology of harmful cyanobacterial blooms that threaten freshwater ecosystems around the world, using Lake Erie as a natural laboratory.
