Donald Kennedy has served since June 1, 2000, as editor-in-chief of Science, the prestigious weekly international journal of the American Association for the Advancement of Science (AAAS). He was named to this position by the AAAS Board of Directors in November 1999, when he was described by former Board Chair M.R.C. Greenwood as having "a broad understanding of current science issues, a wealth of experience in government and university, and incomparable insight." Donald is president emeritus of Stanford University and a former commissioner of the U.S. Food and Drug Administration (FDA). A biologist by training, Donald’s research has focused on exploring how the natural and social sciences can contribute to improving environmental practices and institutions. His specific areas of expertise range from global climate change to the ecosystem impacts of alien marine species invasions. He is Bing Professor of Environmental Science at Stanford, and co-chairs an interdisciplinary center devoted to the development of policies regarding such environmental problems as major land-use changes, economically driven alterations in agricultural practice, global climate change and the development of regulatory practices. Donald served for 12 years as president of Stanford. His leadership there was marked by renewed attention to undergraduate education and by increased student interest in volunteer work and public service. During his presidency, Stanford concluded the largest capital campaign in the history of higher education, added substantially to the quality of its faculty, and cemented its ranking as one of the nation's top research universities. Donald received his A.B. and Ph.D. degrees in biology from Harvard University. He took leave from Stanford in 1977 to serve as FDA Commissioner, then returned to academia in 1979. He served for a year as Stanford's Provost before assuming the university's presidency. A member of the National Academy of Sciences, Donald also maintains membership in the American Academy of Arts and Sciences and the American Philosophical Society. His former Ph.D. students now hold tenured faculty positions at Cornell, Emory, Stanford, Washington, and Yale Universities, Smith and Bryn Mawr College, and the Universities of California, Connecticut, Texas, and Washington.
