Previously an investigator at the International Criminal Court, where I initiated and promoted the use of open source investigative techniques to investigate and prosecute atrocity crimes. Part of the team that established the world's first social media news agency, Storyful, where we built the field of social media event detection, analytical fact-finding and verification.
