Izquierdo's research examines three distinct but interconnected domains:
- self-declared feminist international humanitarian organizations
- women-led grassroots organizations and collectives
- crisis-affected women's own organising initiatives
Drawing on 11 months of ethnographic and interactive research conducted across Bogotá, Norte de Santander, Cauca and Putumayo departments between 2022 and 2023, Izquierdo uses multiple qualitative methods, including participant observation, semi-structured dialogues, collective discussions and storytelling circles with 108 research participants.
She challenges the narrow framing of humanitarian action as the activities and systems put in place by international actors by examining how feminist approaches contribute to shaping alternative forms of humanitarian action in Colombia, a context characterized by prolonged internal armed conflict, disasters and mixed migration flows.
Her research thus centres on the unrecognized or actively refused everyday practices of diverse actors, particularly women and feminists.
