George A. Lopez (Syracuse University, 1975) is the Hesburgh Professor of Peace Studies Emeritus at the Kroc Institute, University of Notre Dame.  He came to the University of Notre Dame as a founding faculty member of the Joan B. Kroc Institute for International Peace Studies in 1986 and was appointed to the Rev. Theodore M. Hesburgh, C.S.C., chair in Peace Studies in 2007.  During his 27 years of teaching at the University he won numerous teaching awards.  Lopez created and has served as Director of the Kroc Institute’s annual Summer Institute on Teaching Peace in the 21st Century since its inception in 2009. This program has assisted the development of peace research and studies programs in over 100 higher education institutions across five continents.  

Lopez's research interests focus on the problems of state violence, especially economic sanctions, gross violations of human rights, and ethics and the use of force. His work has been published in a wide range of social science and policy journals.  Since 1992, Lopez has advised various international agencies and governments regarding sanctions issues, ranging from limiting their humanitarian impact to the design of targeted financial sanctions.  He has written 35 articles and book chapters, as well as authored/ edited six books [often with David Cortright], including The Sanctions Decade: Assessing UN Strategies in the 1990s and Putting Teeth in the Tiger: Improving the Effectiveness of Arms Embargoes [with Michael Brzoska]. 

With Cortright and Alistair Millar, Lopez wrote "Winning Without War: Sensible Security Options for Dealing with Iraq" in October 2002. This policy brief was called the most influential document for those favoring an alternative to war with Iraq. Lopez and Cortright’s research detailing the unlikely presence of weapons of mass destruction in Iraq appeared before the war in “Disarming Iraq” in Arms Control Today (Sept. 2002) and then further articulated after the war in “Containing Iraq: the Sanctions Worked” in Foreign Affairs (July/August, 2004). Some of this work was highlighted in the 2006 Notre Dame Magazine article "Global Warning."  For 2015-16 Lopez has undertaken a major research project with the United Nations University entitled The Sanctions Enterprise: Assessing a Quarter-Century of UN Action for Peace, Security and Human Rights and will be published in 2017 by Cambridge University Press.

Lopez’s earlier contributions to peace and security scholarship and practice include chairing the Selection Committee of the Research and Writing Grants Committee of the MacArthur Foundation’s Program in Peace and International Cooperation from 1988 through 1998. From May-December 1997, he served as interim executive director of the Bulletin of the Atomic Scientists, and then chaired its Board of Directors until June 2003, presiding over the moving of the hands of The Doomsday Clock in 2002. 

From September 2013 – July 2015 Lopez served as the Vice President of the Academy for International Conflict Management and Peacebuilding at the United States Institute of Peace, Washington, DC.  From October 2010 through July 2011, he served on the United Nations Panel of Experts for monitoring and implementing UN Sanctions on North Korea.  He won and held a Senior Jennings Randolph Fellowship at USIP in 2009-10.   As a senior research associate at the Carnegie Council on Ethics and International Affairs in 2001-02, he assisted in the Council’s post- 9-11 public programming in New York City and throughout the US.  

In May 2016 he was named a Judge for the ground-breaking MacArthur Foundation Program 100&Change
