John Melack attended Cornell University (B.A. in Biological Sciences) and Duke University (Ph.D. in Limnology), held a postdoctoral fellowship at the University of Michigan, and has been on the faculty of the University of California, Santa Barbara, since 1977. His honors include being an elected Fellow of the American Association for the Advancement of Science and American Geophysical Union and as a Blaustein Visiting Professor at Stanford University
John Melack's research has emphasized ecological processes in lakes, wetlands, and streams, and hydrological and biogeochemical aspects of catchments. He has conducted multi-year studies of freshwater and saline lakes in eastern Africa and floodplains in the Amazon and Pantanal of South America. In California, his studies of the saline Mono Lake and high-elevation lakes in the Sierra Nevada have continued for over 30 years, and he is involved in an LTER examining linkages among coastal watersheds, near-shore kelp ecosystems, and offshore waters in Santa Barbara Channel. He has applied active and passive microwave and optical remote sensing to studies of lakes and tropical wetlands.
