Anthropologist with a specialization in long-term social change in postcolonial Africa. Recent work focuses on the interaction between law and politics in state formation. Supplementary interests in epistemic decolonization, and in the legal frameworks around extractivist economies, especially in connection with indigenous communities.

My research interests include internal and cross-border displacement in Sub-Saharan Africa, politics of belonging, identity building and state formation. In my ethnographic Doctoral Study I use the return migration of Zimbabweans from neighbouring Southern African countries as an avenue for exploring the dynamics of returnee urban emplacement.

I am currently writing my doctoral thesis on the motivations of Finnish foreign relations towards Southern African states in the latter part of the 1980s. The primary aim of this research is to examine why the relations towards African states were promoted and what were the reasons for doing so. My previous scientific publications focus on Finnish foreign relations and policies towards Southern African states during the Cold War period, and modern cultural impacts of sports video games. My scientific interests include Nordic historical approaches on development cooperation, Finnish foreign, security, and domestic policy issues during the Cold War, African countries in international forums during the Cold War, and modern cultural impacts of sports in society.
