Rita Colwell is a Distinguished University Professor both at the University of Maryland at College Park and at Johns Hopkins University Bloomberg School of Public Health, senior advisor and chairman emeritus at Canon US Life Sciences, Inc., and president and CEO of CosmosID, Inc.
Her research interests are focused on global infectious diseases, water, and health. Colwell is currently developing an international network to address emerging infectious diseases and water issues, including safe drinking water for both the developed and developing world.
Colwell served as the eleventh director of the National Science Foundation (NSF) from 1998 to 2004. In her capacity as NSF director, she served as co-chair of the Committee on Science of the National Science and Technology Council.
One of Colwell's major interests is K-12 science and mathematics education, graduate science and engineering education, and the increased participation of women and minorities in science and engineering.
She has held many advisory positions in the U.S. government, nonprofit science policy organizations, and private foundations, as well as in the international scientific research community. Colwell is a nationally-respected scientist and educator, and has authored or co-authored 17 books and more than 750 scientific publications. She produced the award-winning film, "Invisible Seas," and has served on editorial boards of numerous scientific journals.
Before joining NSF, Colwell was president of the University of Maryland Biotechnology Institute and a professor of microbiology and biotechnology. She was also a member of the National Science Board from 1984 to 1990.
Colwell has previously served as chairman of the Board of Governors of the American Academy of Microbiology, as well as president of the American Association for the Advancement of Science, the Washington Academy of Sciences, the American Society for Microbiology, the Sigma Xi National Science Honorary Society, and the International Union of Microbiological Societies. She is a member of the National Academy of Sciences, the Royal Swedish Academy of Sciences, Stockholm, the Royal Society of Canada, the American Academy of Arts and Sciences, and the American Philosophical Society. She is immediate past-president of the American Institute of Biological Sciences (AIBS).
Colwell has been awarded 55 honorary degrees from institutions of higher education, including her alma mater, Purdue University. She is the recipient of the Order of the Rising Sun, Gold and Silver Star, bestowed by the Emperor of Japan; the 2006 National Medal of Science, awarded by the President of the United States; and the 2010 Stockholm Water Prize, awarded by the King of Sweden.
Colwell is an honorary member of the microbiological societies of the UK, Australia, France, Israel, Bangladesh, Czechoslovakia, Royal Irish Academy and the U.S. She has held several honorary professorships, including the University of Queensland, Australia. A geological site in Antarctica, called Colwell Massif, has been named in recognition of her work in the polar regions.
