As Professor of Social Gerontology in the Population Health Sciences Institute, I co-lead Newcastle University's Centre for Ageing and Inequalities. I joined Newcastle in 2016, having previously been Director of the Irish Centre for Social Gerontology, NUI Galway, Ireland (2010-15). I completed my undergraduate studies in Combined Honours (German and Politics) at Newcastle University in 1985 before moving on to Aston University where I was awarded a PhD in Political Science in 1990. I have since held teaching and research posts at Bangor University, Keele University and the University of Applied Sciences in Worms, Germany.
From 2019 to 2022, I am President of the British Society of Gerontology I am a Fellow of the UK Academy of Social Sciences, have held visiting professorships at NUI Galway, the University of Manchester, Keele University and the University of Vienna.

My research addresses issues relating to social inclusion and exclusion in later life, often with a focus on the spaces and places in which inclusion and exclusion arise and on the policy responses to forms of exclusion. My work has been supported by major grants from the Economic and Social Research Council, the Medical Research Council, the Engineering and Physical Sciences Research Council and The Atlantic Philanthropies. Research findings have been published in such journals as Journal of Gerontology: Social Sciences, The Gerontologist, European Journal of Ageing, Ageing and Society, and Journal of Rural Studies. My most recent book, Social Exclusion in Ageing Societies: Interdisciplinary and Policy Perspectives (co-edited with Kieran Walsh, Sofie Van Regenmortel and Anna Wanka, Springer, 2021), is available to download for free here. With Chris Phillipson and Toni Calasanti, I co-edit the Ageing in a Global Context book series for The Policy Press.
In 2017, working in collaboration with colleagues at ILC-UK, I led a team commissioned by Centre for Ageing Better to produce a scoping review on inequalities in later life. This work highlights the persistent and deep-seated nature of inequalities affecting people aged 50 and over in England.
I am currently involved in three major, multi-centre projects. In the CIVEX project, I am collaborating with colleagues from Belgium, Finland, Spain and Sweden on a study that explores features of civic engagement in later life. In the ADMISSION UK Multimorbidity Research Collaborative on Multiple Long-Term Conditions in Hospital, I am part of a team exploring inequalities in people's experiences of hospitalisation. In the Centre for Digital Citizens, I am collaborating on work that challenges age-based biases in digital technologies.
