Newman is best known for research on form-fitting spacesuits that use mechanical counterpressure to provide greater freedom of motion for astronauts than conventional suits. "Ultimately, the big advantage is mobility, and a very lightweight suit for planetary exploration," Newman said in a Sept. 18 press release from MIT about her group's research.

She has also been involved in science and technology policy. She has a master's degree in technology and policy from MIT and since 2003 has served as director of its Technology and Policy Program.
