Marcia F. Bartusiak is an author, journalist, and Professor of the Practice Emeritus of the Graduate Program in Science Writing at the Massachusetts Institute of Technology. Trained in both communications (B.A. from American University, 1971) and physics (M.S. from Old Dominion University, 1979), she writes about the fields of astronomy and physics.^[1] Bartusiak has been published in National Geographic, Discover, Astronomy, Sky & Telescope, Science, Popular Science, World Book Encyclopedia, Smithsonian, and MIT Technology Review.^[2] The author of seven books, she is also a columnist for Natural History magazine.^[3]

Bartusiak started her career in 1971 as the first female reporter at WVEC-TV (ABC affiliate) in Norfolk, Virginia. She also served for a period as the station's first female anchor before leaving in 1975 to begin a graduate education in physics. After receiving her master's degree, she became a charter member of the writing staff of Discover magazine, when it first started up in 1980, and then began a freelance science-writing career in 1982. ^[4] In 2003, she joined the faculty of the MIT Graduate Program in Science Writing, retiring in 2019 as a professor emeritus.
