Lisbeth Gronlund is a Research Affiliate in the Laboratory for Nuclear Security and Policy in MIT’s Department of Nuclear Science and Engineering.
She has worked on technical and policy issues related to nuclear weapons, missile defenses, and space weapons for over three decades. She spent most of that time—from 1992 to 2020—at the Union of Concerned Scientists’ Global Security Program, where she was a Senior Scientist and, beginning in 2002, also the Co-director of the program.
Believing that a sound democracy requires independent and well-informed critique of government policy, she has devoted her career to using her scientific background to (1) analyze US nuclear weapons and missile defense programs, counter false government claims and propose alternative plans; (2) provide information to members of Congress, the public and media; and (3) increase the scientific knowledge base relevant to these issues. Accordingly, she has written about technical and policy issues for both lay and expert readers and given talks about these issues to both lay and expert audiences.
She holds a Ph.D. in theoretical physics from Cornell University, and is a fellow of the American Physics Society and the American Association for the Advancement of Science.
