François M. M. Morel
François M. M. Morel is a French-American biogeochemist. He is known for his research on ocean acidification, mercury pollution, the only known cadmium metalloenzyme, and the interactions between trace metals and microorganisms. Early life and education 
Morel grew up in Versailles, France. Morel attended the University of Grenoble, France and earned his B.S. in Applied Mathematics in 1966. He went on to earn his Diplôme d’Ingénieur the next year in 1967. In 1971, Morel obtained a Ph.D. in Engineering Sciences from California Institute of Technology. Research and career 
From 1973 to 1994, Morel was a faculty member of the Massachusetts Institute of Technology's Department of Civil and Environmental Engineering, and, from 1994 to 2018, he was a professor in Princeton University's Department of Geosciences. His research and that of his students and postdoctoral researchers dealt the interactions between the chemical composition of natural waters and aquatic microorganisms. The development of computational methods to quantify the reactions among the many chemical species in aquatic systems provided the means to study quantitatively the interactions between microbes and chemical elements and compounds present in natural waters, with a focus on essential metals that are required for the growth of phytoplankton. This work encompassed the cycling and methylation of mercury, the contributions of metals to the nitrogen cycle, the use of cadmium by marine microalgae, the uptake mechanisms of iron and zinc by plankton, and the effects of ocean acidification on microorganisms. REDEQL 
As a postdoctoral fellow in Environmental Engineering Sciences from 1971-1973, Morel collaborated with James (Jim) J. Morgan to produce the computer program REDEQL (where RED stands for "redox" and EQL stands for "equilibrium"), which computed complex chemical equilibria in natural waters and man-made chemical systems. Morel and Morgan's creation of REDEQL was supported by the United States Environmental Protection Agency and was widely adopted and built upon. Ocean acidification 
In 2009, Morel chaired the Committee on the Development of an Integrated Science Strategy for Ocean Acidification Monitoring, Research, and Impacts Assessment. This committee published the report Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean, which detailed the unprecedented acidifying of the ocean's pH due to anthropogenic carbon dioxide emissions, the potential adverse impacts on marine organisms dependent on calcium carbonate, and the need for more information and international cooperation. Appointments 
Morel founded and directed the Center for Environmental BioInorganic Chemistry from 1998 to 2007. From 1998–2004 and from 2014–2017, Morel served as the director of Princeton Environmental Institute, which was later renamed to the High Meadows Environmental Institute in 2020. Retirement 
Morel retired in 2018. Awards and honors
