Stephanie Sanok Kostro is deputy director of the Center for Strategic International Studies (CSIS) International Security Program, where she focuses on a range of issues affecting defense, foreign affairs, and international development. Her research interests include defense policy and strategy, U.S. government stabilization and reconstruction efforts, the nexus between security and economic development, transitions of post-conflict responsibilities, and U.S. military activities to partner with foreign nations and other organizations.
Prior to joining CSIS, Mrs. Kostro served at the U.S. embassy in Baghdad, where she developed policy options for the U.S. government's efforts to support a sovereign, stable, and self-reliant Iraq. She contributed to the Joint Campaign Plan—an interagency strategy to strengthen U.S. relations with Iraq along political, economic, energy, rule of law, and security lines of operation and identify strategic risks and transition issues related to the U.S. military withdrawal.
Ms. Kostro served as a senior professional staff member on the U.S. House of Representatives Committee on Armed Services, where she led a team on overarching defense policy topics. She also worked at the Pentagon from 1998 to 2005 in the Secretary of Defense's counter-proliferation, European, and NATO policy offices as a Presidential Management Fellow.
Mrs. Kostro received a master of public policy degree with concentrations in international security policy and conflict resolution from Harvard University and a degree in communication and international relations from Cornell University.
