Sergio Guillén is a scholar and practitioner in public policy, conflict resolution, and democratic deliberation, with extensive experience in social and environmental governance and dialogue. He earned his Ph.D. from the Crawford School of Public Policy at the Australian National University (ANU), where he focused on the plurality practices enacted by social movements used to engage with spaces for public deliberation. He has taught university-level courses on engineering ethics, natural resource governance, environmental security, international negotiations, and public interest conflict management. 

He worked for over a decade on sustainable energy policy and finance throughout Latin America, collaborating with leading U.S. government agencies, multilateral banks, and public interest organizations involved in international clean energy policy and rural electrification. Encountering multiple public interest conflicts related to energy infrastructure prompted him to become a certified mediator, and accredited as a conciliator of the Conflict Resolution Center of the Costa Rican Professional Body for Engineers and Architects (CFIA-CRC).

Sergio has worked for over 20 years as a researcher, practitioner, and trainer of public interest conflict analysis and resolution throughout Latin America. His work includes transboundary water management, labor relations, participatory policy analysis, and land-use management.
