Sam Gregory helps people use the power of the moving image and participatory technologies to create human rights change. He is Program Director at WITNESS, a leading organization that supports people to use video for human rights, and teaches on human rights and participatory media at the Harvard Kennedy School. Gregory launched the Webby-nominated Human Rights Channel on YouTube, and leads WITNESS’ work on the award-winning ObscuraCam and InformaCam tools. He speaks and writes widely on human rights and new technologies, focusing on citizen media as powerful human rights evidence, and promoting new understandings of anonymity in visual media. He has worked on impactful campaigns worldwide (particularly in South-East Asia and Latin America), and created innovative training programmes and teaching texts. Gregory was a 2010 Rockefeller Foundation Bellagio Resident on the future of video-based advocacy, and in 2013 was a 'Future for Good' Fellow at the Institute for the Future, working on 'co-presence for good' and the human rights engagement and advocacy possibilities of live video and immersive witnessing combined with contextual task-routing to solidarity supporters and “distant witnesses”. Gregory has an MA in Public Policy from the Harvard Kennedy School, attending as a Kennedy Memorial Scholar.
