Sam Gregory

Programme Director


Sam Gregory is the Program Director of WITNESS, which helps people use video and technology to defend human rights. Sam’s current work focuses on the threats and opportunities as emerging technologies such as AI intersect with disinformation, media manipulation, and rising authoritarianism. An expert on new forms of misinformation and disinformation as well as innovations in preserving trust and authenticity, he leads WITNESS’ global ‘Prepare, Don’t Panic’ work on emerging threats such as deepfakes, emerging solutions such as authenticity and provenance infrastructure, and on new opportunities such as live-streamed and co-present storytelling for action and smartphone witnessing for human rights.


Quoted in major media worldwide, he has spoken at Davos and the White House and publishes frequently on issues in technology and human rights. He is a former Young Global Leader of the World Economic Forum, and is on the Technology Advisory Board of the ICC. He previously taught from 2010 to 2018 on participatory media and human rights at the Harvard Kennedy School, and co-chaired the Partnership on AI’s Expert Group on AI and the Media.
