The Principal Investigator of this project is Dara Kay Cohen (Harvard University). Ragnhild Nordås (PRIO) is a core resaercher on the project as a sub-contractor at PRIO. The project will create the most comprehensive cross-national dataset to date on wartime gender-based violence. A number of theoretical questions can be examined with such data. In a pilot study, the researchers found that gender-based violence by armed actors continued, often for years, after the official end of the war and cessation of lethal violence. This and other questions can be examined more conclusively with the new dataset generated by this research.
