CGHR Research Associates

Dr Stephanie Diepeveen

-Deputy Director-

Dr Stephanie Diepeveen is deputy director and a CGHR Research Associate on the theme of Digital media, voice and power. Her research looks to take a historical perspective on recent and profound changes brought about through digital media, specifically on the African continent. Her individual research has focused on digital media in Kenya and eastern Africa, specifically how digital media intersect with everyday politics and forms of public participation. Her PhD research, conducted within the Department of Politics and International Studies at Cambridge, examined the nature and political possibilities of everyday publics in Mombasa, Kenya, looking at the manifestation of ‘people’s parliaments’ on the streets and online through Hannah Arendt’s ideas about the public realm. Looking forward, she is increasingly interested in the intersection of digital media and political authority in contemporary politics on the African continent.

Dr Gyda Marås Sindre


Gyda joined CGHR in 2015 as a Marie Curie Fellow (co-funded by the European Research Council and the Research Council of Norway) with the project: Post-conflict Political Parties: Party formation, organisation and institutionalisation in the context of peacebuilding and democratisation. The project asks what characterises political parties that are formed in the aftermath of war and to what extent are they able to aggregate, channel and express political grievances and contribute to conflict management and democratisation? Based on a cross-regional comparison of relevant parties in three post-conflict contexts, Burundi, Bosnia and East Timor, the project aims to provide insights into the specific challenges linked to political parties in the aftermath of war. Gyda will be drawing on CGHR's resources and expertise on peacebuilding, collaborating with Devon Curtis and others; organising academic and practitioner workshops; using CGHR’s practitioner network to establish dialogue on the role of political parties in peacebuilding (especially rebel-to-party transformation), and using the CGHR platform to develop a research agenda on political parties and peacebuilding.
