Dr Sue Caton is an Associate Professor in Intellectual Disabilities Research in the Department of Social Care and Social Work at Manchester Metropolitan University, UK. Sue completed a PhD on the transition to adult life at the same university in 2002 and has carried out research with people with intellectual disabilities for the last 25 years. Sue’s research uses a social justice approach to identifying and understanding both social and health inequalities. This has included research around digital participation, the social and health inequalities that materialized during the COVID-19 pandemic, and more recently the Medications and My Mental Health co-produced project which aimed to develop a toolkit of information and resources to support people with intellectual disabilities to become more confident shared decision-makers about their mental health medications: https://medmentalhealth.net/. Methodologically, Sue’s research is primarily qualitative, using co-production and participatory and creative approaches. Most of Sue’s research is carried out in partnership with small organizations such as self-advocacy groups and includes co-researchers with learning disabilities as part of the research team.
