War begets crises that are among the most urgent areas requiring help from the international HCI/CSCW community; yet too few scientists address it using context-based, participatory field methods and by engaging in country and regionally based, longitudinal partnerships. Drawing on the author's ongoing eight-year engagement as a design ethnographer with UNHCR Jordan and region for the Syrian War, this paper discusses Humanitarian Research as a framework for guiding HCI/CSCW research in conflict zones with displaced persons. Based on the principle of "People First, Data Second," Humanitarian Research is explained with illustrative examples along with the nature of war and UNHCR's protection mandate, the research challenges and ethical roles of HCI scientists in conflict zones and how these roles entwine with refugee stakeholders, NGOs, country actors, and university IRBs.
