Marc Luy is head of the research group “Health and Longevity” at the Vienna Institute of Demography (VID) and Director of the German-Austrian “Cloister Study”. His research focuses on differentials in health and longevity with the long-term goal of disentangling the complex causation mechanisms of healthy ageing. The studies include differences between specific subpopulations—such as women and men or socioeconomic status groups—as well as differences between countries or smaller regional units. A further field of work is the development of demographic methods and their empirical application, for instance regarding mortality tempo adjustment and indirect estimation of adult mortality. Luy has received several awards and stipends, including the Gunther Beyer Award of the European Association for Population Studies (EAPS) in 2003 and an ERC Starting Grant in 2010. In 2011 he was elected into the Austrian Academy of Sciences as member of the “Young Academy”, and in 2016 as Corresponding Member of the Division of Humanities and the Social Sciences. Since 2014 he is also member of the Commission for Science Ethics of the Austrian Academy of Sciences, and he served as Secretary-General of EAPS from 2012 to 2016. Luy has taught Demography at the Universities of Rostock, Mainz and Frankfurt/Main and is still teaching “Indirect Demographic Estimation Techniques” at the European Doctoral School of Demography.
