Raquel is a lawyer specialized in helping communities use technology to expose human rights abuses and seek accountability for international crimes. At WITNESS, she leads a team that engages early on with emerging technologies that will undermine or enhance audiovisual witnessing, and that will impact thousands of human rights defenders. Her current work focuses on how generative AI and synthetic media affect the trustworthiness of digital content related to critical human rights situations; and on the challenges of accessing, collecting and archiving social media content that could be used for justice for core international crimes. Raquel holds over a decade of experience working on matters concerning the verification, provenance and authenticity of digital content. She is regularly consulted by international accountability institutions, technology companies, and groups documenting core international crimes on matters related to the use of digital evidence in legal proceedings, in particular photo and video.
