Senior Freshwater Scientist
Jeff Opperman, senior freshwater scientist, has been working to protect rivers and lakes for nearly 15 years. He has provided strategic and scientific guidance to freshwater conservation projects across the United States as well as in China, Africa and Latin America. In his role at The Nature Conservancy much of Jeff’s focus is on improving the environmental sustainability of hydropower both by advancing sound policies and by supporting on-the-ground projects.

He is a member of the governing board of the Low Impact Hydropower Institute (LIHI), which certifies “environmentally preferable” hydropower and recently served on an Independent Review Panel that provided recommendations for floodplain management to California’s Department of Water Resources.
Jeff earned his B.S. in Biology from Duke University and a Ph.D. in Ecosystem Science from the University of California, Berkeley. He then studied floodplain ecology during a post-doctoral fellowship at the University of California, Davis. His scientific and policy research has been published in journals such as Science, BioScience and Ecological Applications. Jeff strives to communicate the challenges and opportunities of protecting fresh water through his “Cool Green Science” blog on nature.org.
