Prof Carol Jagger is the AXA Professor of Epidemiology of Ageing in the Population Health Sciences Institute at Newcastle University. Her research programme spans demography and epidemiology with a focus on mental and physical functioning in ageing and has three themes: Understanding variations in Healthy Active Life Expectancy; Disability and Functioning in Later Life; and Ageing Population Projections for Policy. Acknowledged as the leading UK researcher on healthy life expectancy, she regularly provides evidence on this topic to various government committees. She is a Chartered Statistician, a Fellow of the Royal Statistical Society and the Gerontological Society of America, and an Honorary Fellow of the Institute and Faculty of Actuaries.

Eileen Crimmins is the AARP Chair in Gerontology, and University Professor at the Davis School of Gerontology at the University of Southern California in Los Angles.

She is a member of the National Academy of Sciences, the National Academy of Medicine, and fellow of the American Association for the Advancement of Science. She received her PhD in Demography from The University of Pennsylvania. Crimmins' research is in the area of factors promoting healthy aging and healthy life expectancy which examines the interaction of trends in life expectancy and population health. She has received the Kleemeier award for research from the Gerontological Society of America and the Matilda White Riley Distinguished Scholar Award from the Section on Aging and the Lifecourse of the American Sociological Society.

Prof Dr. Herman Van Oyen is Scienfic Director Epidemiology and public health at Sciensano, the Belgian federal research institute of population health and Professor Epidemiology at the Faculty of Medicine (Public Health and Primary Care) and Faculty of Science (Statistics) at University of Ghent . He has been the major driver in the development of the GALI, the Global Activity Limitation Indicator. GALI measures participation restriction and is the disability indicator of the Healthy Life Years. His current research focus on knowledge translation methods related to Health Expectancy, especially the contribution of diseases and life styles to variations in Health Expectancies and more general in the development of a Health Information Impact Index.

Prof Jean-Marie Robine is an Emeritus Research Professor at INSERM, the French National Institute of Health and Medical Research and Emeritus Professor at the advanced school Ecole pratique des hautes études in Paris. He studies human longevity, with the aim of understanding the relations between health and longevity. In particular, he measures the impact that the increase in adult life durations may have on the health status of the older population. In his most recent work, he takes into account climate changes.
