Tilly Harris is a Multimedia Journalist trained in print, digital, radio & TV reporting. She has experience across leading national newsrooms like the Times, Financial Times, the Daily Mail & Mail on Sunday, and The Telegraph. She currently works at The Sun and the BBC .
She holds an MA in Broadcast Journalism from City, University of London, where she trained in self-shooting, camera and audio operation, and post-production editing in Premiere and After Effects. Alongside her studies she worked as a Production Runner on Sunday with Laura Kuenssberg.
Her recent investigations have exposed the platforms and institutions meant to protect vulnerable groups. At the Mail on Sunday, she brought an investigation into AI-generated violent content bypassing TikTok's Restricted Mode parental controls, examining how AI studios have been able to produce and circulate graphic material that evades the platform's safeguards. She built her report after months of conversations with child-safety specialists. It coincides with Ofcom's July 2026 investigation into TikTok and Meta's $18 billion settlement over the harm its platforms caused children, a deal that explicitly pressures TikTok and YouTube to adopt stronger safety protections.
At The Times this year, after following the wider debate in AI-generated writing she uncovered fabricated AI-generated citations running through an academic book published by Springer Nature. After verifying these faulty citations through associate professor Guillaume Cabanac and Dr Nathan Camp, the book was subsequently recalled by the publisher. The story went on to be discussed by senior academic figures and appears in Retraction Watch and AI Incident Database.
At The Telegraph in 2025, she exposed how NHS support for FGM survivors in the UK was falling short in practice. She spoke to Leyla Hussein, the campaigner and FGM survivor to speak on the record, along with two NHS midwives who broke ranks to speak out, and a German surgeon offering reconstructive treatment that survivors can't get on the NHS. This piece forced culpability of the lack of comprehensive treatment available to survivors of female genital mutilation.
