Seeing Isn't Believing
how AI-generated images are reshaping public trust in vaccines and health, and what communities can do about it.
My current UKRI Smart Data Research UK Fellowship develops Synthetic-media Discourse Analysis (SDA): a methodology that pairs
AI-assisted detection of synthetic media (AI-generated images and video) with human-led qualitative discourse analysis and community-participatory methods. Its open-source tool, SDA Vision, calibrates how synthetic an image appears and explains the signals behind that judgement, keeping interpretation with the researcher and the public rather than returning a black-box score.
The research tracks how AI-generated imagery enters, spreads and disrupts health conversations across major social platforms, and works directly with affected communities through workshops, co-produced literacy resources and public dialogue.
Funded by ESRC through Smart Data Research UK, 2026-2027.

About Me
Senior Research Fellow · Digital Sociologist · Methodologist
I'm a researcher and methodologist specialising in Big Qualitative Data. I develop methods for making sense of the vast, messy, multilingual qualitative data that floods social media platforms every day. I currently hold a UKRI Smart Data Research UK Fellowship at Manchester Metropolitan University, and I am also based at the Vaccines and Society Unit (Oxford Vaccine Group, University of Oxford), where I research vaccine hesitancy, digital misinformation and health discourse.
At Oxford I co-supervise doctoral researchers, including Charlie Firth (DPhil, Paediatrics), alongside Professor Sir Andrew Pollard and Professor Samantha Vanderslott) and Kate Joynes-Burgess (DPhil, Oxford Internet Institute)alongside Professor Samantha Vanderslott and Professor Phil Howard).
My work sits at the intersection of digital sociology, computational methods, and public health. I've spent over eight years developing innovative approaches to qualitative research at scale, working with organisations including the Wellcome Trust, UNICEF, and WHO across 16 countries and 12 languages.
I co-created the LISTEN framework for rapid, collaborative qualitative analysis of big data; founded Synthetic-media Discourse Analysis (SDA) for making sense of AI-generated visual content in public discourse; and built the Visual AI Literacy (VAIL) toolkit for community education.
I believe powerful research methods shouldn't be locked behind expensive software or institutional gatekeeping. This website exists to make these approaches accessible to anyone working with large-scale qualitative data, whether you're an academic researcher, a policy analyst, a journalist, or an NGO practitioner.
