Professor Sotomayor’s research focuses on multilateral policy, with an emphasis on Latin America’s involvement in United Nations peacekeeping operations; non-proliferation strategies in Latin America; and trans-national security relations in Mexico. The unifying thread that runs through his research and writing is the interaction between studies on civil-military relations and international security, and research on the conditions and requirements for domestic order and stability in Latin America. The research has involved fieldwork in South, Central, and North America, as well as the Caribbean.

His most recent book The Myth of the Democratic Peacekeeper: Civil-Military Relations and the United Nations (Johns Hopkins University Press, 2014) is a richly detailed study of Argentine, Brazilian, and Uruguayan peacekeeping participation. Sotomayor draws upon international socialization theory and civil-military relations to understand how peacekeeping efforts impact participating armed forces. The book aims to break with a number of conventional theories about the supposed salutary effects of exposing troops to UN missions. The study finds that peacekeeping experiences do not necessarily transform troops in a positive way. Rather than UN transforming its blue-helmets, they often transform the organization’s mission. The book provides further insight into how international factors affect domestic politics as well as how international institutions affect democratizing efforts. 

Sotomayor received his Ph.D. in political science from Columbia University, in New York. He joined the Department of National Security Affairs in 2009. Previously, he held a post-doctoral fellowship position at Tulane University’s Center for Interamerican and Policy Research in New Orleans and was a public policy scholar in the Mexico Institute at the Woodrow Wilson Center for International Scholars, in Washington DC.
