Diana Chigas is Professor of the Practice of International Negotiation and Conflict Resolution at The Fletcher School and also services as Senior International Officer and Associate Provost at Tufts University. As Senior International Officer, she is responsible for leading the development and realization of university-wide global strategy. 

Prior to joining the Provost’s office, Diana was also director of the Reflecting on Peace Practice program and co-director of collaborative learning at CDA, a non-governmental organization dedicated to working with development, humanitarian and peacebuilding practitioners and the private sector globally to improve the effectiveness of international assistance in fragile and conflict-affected contexts. At CDA, Diana focused on systemic approaches to conflict analysis and planning, reflection and evaluation to improve the impact of peace programming. Diana was a contributor to the 2012 OECD DAC guidelines on evaluation of conflict prevention and peacebuilding, and to guidance for the UK on evaluation of peacebuilding and conflict sensitivity.

Diana has over 30 years of experience as a facilitator and consultant in negotiation and conflict resolution. Her work has included development of strategies, training and advice on preventive diplomacy in the OSCE, training for the United Nations and several regional organizations, “track two” dialogue in El Salvador, in South Africa, Ecuador and Peru and in the Georgia/South Ossetia peace process, and facilitation of inter-ethnic dialogue in Cyprus.

Diana currently co-directs the Corruption, Justice and Legitimacy (CJL) Program at Fletcher’s Leir Institute, a research-to-practice initiative that aims to improve the effectiveness of anti-corruption programming in fragile and conflict-affected contexts. Her current research focuses on social norms and corruption, and the intersection of peacebuilding and corruption.
