Diana is an experienced applied anthropologist, qualitative researcher, analyst and policy designer with over 15 years of combined professional experience in academia, think-tanks, international organisations and NGOs. She researches situations of latent and violent conflict and their aftermath and particularly the unseen factors that influence individual and collective behaviour, social and political narratives, and how people understand and experience notions such as justice, authority, peace and security. Specifically, this has taken her to engage in the complex dynamics of conflict management and peacebuilding, public authority and community safety, forced displacement, mixed migration and durable solutions. Her work involves supporting aid agencies in understanding and navigating the volatile environments they operate in, including in ensuring their programmes do no harm and are conflict sensitive.

Diana has published extensively in both academic and policy circles, especially on South Sudan. Her previous work experience includes positions with the Danish Refugee Council, the Norwegian Institute of International Affairs, the Small Arms Survey, the School of Oriental and African Studies, the World Bank and the Delegation of Portugal to the United Nations, among others. She has a PhD from the School of Oriental and African Studies and an MA from the University of Groningen/University of Uppsala.
