Dr. Sotomayor is an international relations scholar whose work is regional, comparative, and qualitative. His research analyzes the impact of international socialization, militarization, and denuclearization in three areas: 1) military operations other than war (MOOTW, including peacekeeping); 2) trans-national and border security; and 3) regional non-proliferation strategies. The unifying thread that runs through my 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 regional stability in Latin America.
