My PhD research intertwines Feminist Peace Research, Sociological neoinstitutionalism and sociology of measurement. I study the measurement practices embedded in National Action Plans (NAPs) for the UN Resolution 1325 on Women Peace and Security (WPS), and particularly, the construction and use of indicators. Indicators have become an increasingly important mechanism of governance, as well as knowledge production, and in my study are understood as social practices allowing me to focus not only on what is being measured but also on its effects on the policy field. The project compiled a global dataset of 7500 indicators harvested from all the NAPs adopted between 2005 and 2020, enabling both spatial and linear windows of inquiry. In addition, an ethnography of WPS indicators in Nigeria (conducted during 2020) provides new knowledge about the role of local actors in translating indicators into practice.
