Diana Chigas is Professor of the Practice of International Negotiation and Conflict Resolution at the Fletcher School of Law and Diplomacy and also services as Senior International Officer and Associate Provost at Tufts University. As Senior International Officer, she is also responsible for leading the development and realization of a 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, as well as the private sector, to improve the effectiveness of international assistance in fragile and conflict-affected contexts. At CDA, Diana focused on systemic approaches to conflict analysis, the role and impact of the private sector in peacebuilding, and strategic 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 DFID on guidance on evaluation of peacebuilding and conflict sensitivity. Diana has over 25 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. Her current research interests include cumulative impacts of peacebuilding and understanding the dynamics of corruption in conflict-affected and fragile contexts in order to develop more effective anti-corruption programming. Through the Institute for Human Security at the Fletcher School, Diana currently co-leads with Cheyanne Scharbatke-Church research in Uganda, DR Congo and Central African Republic on corruption in the criminal justice sector and its relationship to state legitimacy.
