The American Association for the Advancement of Science (AAAS) recently awarded the distinction of fellow to 702 scientists, including CEE’s Sallie W. (Penny) Chisholm, the Lee and Geraldine Martin Professor of Environmental Studies, and four other members of the MIT community. Fellows are recognized by their peers for their scientifically or socially distinguished efforts to advance science or its applications. New fellows will be presented with an official certificate and a gold and blue pin (representing science and engineering, respectively) on Feb. 16, 2013, at the AAAS annual meeting in Boston. Chisholm was elected for her distinguished contributions to biological oceanography, especially for pioneering studies on the most abundant primary producer on the planet, the marine microorganism Prochlorococcus.
