MacArthur “genius” award winner Corinne Dufka was a photojournalist for Reuters, covering armed conflicts in 17 nations. But inside a hotel room in Rwanda, she had an “epiphany” that compelled her to leave photojournalism at the height of her career. Dufka discusses what drives her to champion the rights of the marginalized, whether inside a psych ward in San Francisco, at a rain-soaked refugee crossing in the Democratic Republic of the Congo, or in a Bosnian battlefield, where Dufka herself was severely injured by a landmine. Dufka is now a researcher for Human Rights Watch.
