INTERNATIONAL SECURITY

A Safer Future for Every Nation.

While the challenges have changed over the decades — from building multilateral institutions to managing ascending nuclear powers to confronting extremist threats and escalating humanitarian crises — SIPA continues to produce the conceptual frameworks, practical policies, and experts that help shape international collaboration for the safety of people everywhere.

Providing Guidance to Policy Makers Around the Globe

During her tenure, Dean Janow bolstered SIPA’s already-deep bench of experts who shape international collaboration for the safety of people everywhere.

Stephen Biddle, who joined SIPA in 2018 as professor of international and public affairs, is an expert in security studies who specializes in great power conflict and U.S. defense policy. One of the leading scholars of military affairs of his generation, Biddle is the author of the award-winning, seminal book Military Power: Explaining Victory and Defeat in Modern Battle and, in 2021, Nonstate Warfare: The Military Methods of Guerillas, Warlords, and Militias. 

 

Thomas J. Christensen, a leading expert in Chinese foreign policy and international security, joined SIPA as a professor of international and public affairs. He is co-director of the Columbia-Harvard China and the World Program, which has relocated from Princeton University, where Christensen had been a faculty member since 2003. Christensen’s most recent book, The China Challenge: Shaping the Choices of a Rising Power, was an editors’ choice at the New York Times Book Review and book of the year at Foreign Affairs magazine. 

 

Jean-Marie Guéhenno, a former UN under secretary for peacebuilding, became director of the Kent Global Leadership Program on Conflict Resolution in early 2021. Later that year he was named as SIPA’s Arnold A. Saltzman Professor of Practice in International and Public Affairs — the same position he held with distinction from 2010 to 2014, before departing to become president and CEO of the International Crisis Group.


Tamar Mitts, assistant professor of international and public affairs, uses data science and machine learning to examine the dynamics of conflict and political violence, as well as the causes and consequences of radicalization and violent extremism. Her current research examines the behavior of Islamic State supporters on social media. Mitts is also a faculty member at Columbia University's interdisciplinary Data Science Institute.

Keren Yarhi-Milo, a leading scholar of decision-making in foreign policy, jointly appointed in SIPA and the Department of Political Science, came to SIPA from Princeton. She serves as the Arnold Saltzman Professor of War and Peace Studies and directs the Saltzman Institute

Facing the Future of Contemporary Conflict

The Kent Global Leadership Program on Conflict Resolution was established in December 2019 to help prepare the next generation of practitioners for the increasingly difficult challenges posed by contemporary conflict. The program's foundation is an intensive week-long training session for professionals from governments and inter-governmental institutions. Other essential elements are an annual visiting professorship and fellowships for outstanding SIPA graduate students. Sustained by the generous support and vision of Muhtar Kent, the program is directed by Professor Jean-Marie Guéhenno.
