Jo Holliday

Dr Jo Holliday leads the Scientific Study Development Group for UK Biobank. In this role, she strategically oversees a broad portfolio of enhancement projects—ranging from overseeing the development and rollout of web-based participant questionnaires to scoping out, setting up and managing large scale enhancement projects. She also directs methodological research aimed at maximising participant response rates and sustaining long-term engagement, has responsibility for UK Biobank’s participant communication strategy and coordinates the department’s online questionnaire-sharing service.

Since joining Oxford in 2015, Jo has held progressive roles within UK Biobank including Research Facilitator in Epidemiology, Health Data Group Lead and, most recently, Scientific Study Development Lead (from 2024). Each of these roles has focussed on enhancing UK Biobank’s capacity to deliver innovative, participant-centred data collection initiatives.

Prior to her time at Oxford, Jo spent 14 years in the School of Social Sciences at Cardiff University—where she also earned her PhD—serving as Project and Trial Manager for numerous public health studies focused on child and adolescent health. Her experience spans complex intervention trials, secondary data analysis, and policy evaluation.
