Starting in 2015, Tabatabai worked as a researcher for the southern California-based
RAND Corporation think tank. She was then a curriculum director and visiting associate professor of security studies at Georgetown University, an international civilian consultant for
NATO, and a former Middle East Fellow at the Alliance for Securing Democracy at the
German Marshall Fund of the United States. After the Biden administration took office in January 2021,
Robert Malley was appointed to lead U.S. nuclear negotiations with Iran, with Tabatabai appointed as a team member. She departed the negotiating team (along with
Richard Nephew) after a few months because she believed that the U.S. would lift too many sanctions on Iran and consequently, a reinstated agreement would not be strong enough. Tabatabai is a member of the
Council on Foreign Relations. == Controversies ==
