I hold the AXA Chair in Epidemiology of Ageing in the Institute for Ageing and Health. My first degree was in mathematics and I hold an MSc in Statistics from the University of Leeds and a PhD in Statistics from the University of Leicester. From 1981 until 2010 I was in the Department of Health Sciences at the University of Leicester. I have an Honorary Visiting Fellowship at the Department of Public Health and Primary care, University of Cambridge.
I am a Fellow of the Faculty of Public Health, Fellow of the Royal Statistical Society (C.Stat) and Chartered Scientist (CSci), Member of the British Geriatrics Society and a Fellow of the Gerontological Society of America.
My research expertise is in the demography and epidemiology of ageing with a focus on late life functioning, both physical and mental, and including measurement as well as determinants and consequences for care. I have been involved in the design and/or analysis of all the major UK cohort and longitudinal studies of ageing. I am acknowledged as the leading UK researcher on healthy life expectancy and its use to monitor population ageing, have published widely on this topic, have regularly provided advice to government departments and committees, and sit on the Institute and Faculty of Actuaries Mortality Research Steering Committee. Internationally I have made major contributions over the last decade to developing the instruments and indicators to monitor population health across the European Union and am currently a member of the Scientific Board of the European Joint Programming Initiative 'More Years, Better Lives'. My current research program has three themes: Understanding variations in Healthy Active Life Expectancy; Disability and Functioning in Later Life; and Ageing Population Projections for Policy.
