Social Demography Seminar with Jessica Finlay

VIRTUAL
Jessica Finlay, PhD, Assistant Professor of Geography, University of Colorado-Boulder, presents ‘Cognability: A mixed-methods approach to neighborhoods and cognitive health across the life course.’
The Social Demography Seminar (SDS) series at the Harvard Center for Population and Development Studies provides a lively forum for scholars from across the University to discuss in-progress social scientific and population research. Social demography includes work that uses demographic methods to describe and explain the distribution of social goods across populations. The hybrid series offers presentations on a wide variety of topics such as family, gender, race/ethnicity, population health—including mortality, morbidity, and functional health—inequality, immigration, fertility, and the institutional arrangements that shape and respond to population processes.

CHDS Seminar with Mark Strong of University of Sheffield, UK

Join the Center for Health Decision Science for a seminar with Mark Strong of the University of Sheffield, UK, School of Medicine and Population Health, “Understanding and Managing Uncertainty in Model-Based Decision Making.” We commonly use computer models to help us make decisions in healthcare resource allocation. Should we fund a particular new drug, for example? However, even with our best model we still might make a wrong decision. This is because we can almost never eliminate uncertainty. This seminar will cover the meaning of uncertainty in a model-based decision making context, and how we can manage it, with particular reference to the quantification of the value of new information.
Mark Strong is Dean of the School of Medicine and Population Health at the University of Sheffield, UK. He is a public health physician and Professor of Public Health, and has conducted research on a wide range of topics relating to public health, health economics, health services research, epidemiology and statistics. He is a Chartered Statistician of the UK Royal Statistical Society and his core research interests relate to the quantification and management of uncertainty in healthcare decision making.
