Her research and work lies at the intersection of gender, religious and development studies and seeks to diversify responses to gender-based violence programmes in the African region. Her PhD study proposed a philosophical deconstruction of Euro-American gender theory and merged a theological analysis of gender, marriage and domestic violence in the Ethiopian Orthodox Täwahәdo Church tradition with a decolonial ethnographic participatory study of conjugal abuse realities and attitudes in the Ethiopian Orthodox community of Aksum, Ethiopia. Dr Istratii specialises in training Ethiopian Orthodox clergy on domestic violence and developing related multilingual resources. She is also involved in numerous inter-faith initiatives and currently co-leads research in Ethiopia, Egypt and the UK to explore Muslim-Christian responses to domestic violence in multi-religious societies. She has previously authored the monograph Adapting Gender and Development to Local Religious Contexts: A Decolonial Approach to Domestic Violence in Ethiopia (Routledge, 2020) and has written and directed the multilingual docudrama ‘Tidar’ (Marriage) in Ethiopia.

As a Research Fellow, Dr Istratii is keen to build on her work and networks in East Africa, Europe and North America to create a platform and space for theologically informed and ethnographically grounded discussions, reflections and responses to gender-related issues and domestic violence in Eastern and Oriental Orthodox communities worldwide. The aim is to achieve a better representation of Orthodox Churches in debates around gender injustices worldwide and to foster a more collective pan-Orthodox response, while improving mutual understanding across Eastern and Oriental Orthodox Church traditions and communities.
