Oriana Skylar Mastro is a Center Fellow at Stanford University’s Freeman Spogli Institute for International Studies (FSI). Within FSI, she works primarily in the Shorenstein Asia-Pacific Research Center (APARC) and the Center for International Security and Cooperation (CISAC) as well. She is also a fellow in Foreign and Defense Policy Studies at the American Enterprise Institute.

Mastro is an international security expert with a focus on Chinese military and security policy, Asia-Pacific security issues, war termination, and coercive diplomacy. Her research addresses critical questions at the intersection of interstate conflict, great power relations, and the challenge of rising powers. She leverages process tracing, qualitative historical analysis, and the case study method with the goal of conducting policy-relevant research. She has published widely, including in Foreign Affairs, International Security, International Studies Review, Journal of Strategic Studies, The Washington Quarterly, The National Interest, Survival, and Asian Security. Her book, The Costs of Conversation: Obstacles to Peace Talks in Wartime (Cornell University Press, 2019), won the 2020 American Political Science Association International Security Section Best Book by an Untenured Faculty Member.

She also continues to serve in the United States Air Force Reserve, for which she works as a Strategic Planner at INDOPACOM. She has received numerous awards for her military service and contributions to U.S. strategy in Asia, including the 2020 and 2018 Meritorious Service Medal, the 2017 Air Force recognition Ribbon, and the 2016 Individual Reservist of the Year Award.

Prior to her appointment at Stanford in August 2020, Mastro was an assistant professor of security studies at the Edmund A. Walsh School of Foreign Service at Georgetown University.
