She was also a member of the National Science Board from 1984 to 1990.
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 19 books and more than 800 scientific publications. She produced the award-winning film, "Invisible Seas," and has served on editorial boards of numerous scientific journals, including GeoHealth, which she founded at AGU in 2015.
Dr. Colwell has previously served as Chairman of the Board of Governors of the American Academy of Microbiology and also 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, the International Union of Microbiological Societies, and the American Institute of Biological Sciences (AIBS).
Dr. Colwell is a member of the U.S. National Academy of Sciences, the Royal Swedish Academy of Sciences, Stockholm, the Royal Society of Canada, the Royal Irish Academy, the Bangladesh Academy of Science, the Indian Academy of Sciences, the American Academy of Arts and Sciences, and the American Philosophical Society. 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.
Colwell has been awarded 62 honorary degrees from institutions of higher education, including her alma mater, Purdue University.
A geological site in Antarctica, called Colwell Massif, has been named in recognition of her work in the Polar Regions.
Colwell has published a new book, "A Lab of One's Own: One Woman's Personal Journey Through Sexism in Science" Learn more here.
