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 to the “Young Academy” of the Austrian Academy of Sciences and at the 2012 European Population Conference he was elected Secretary-General of EAPS. Since 2014 he is also member of the Commission for Science Ethics of the Austrian Academy of Sciences. 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.
