Stephanie is a Reader in Economics at the University of Bristol and an Endowed Professor of Health Economics at Erasmus University Rotterdam. Her main research interests are in health economics and applied microeconometrics. Her research covers two main areas. First, she is interested in the economics of obesity, diet and nutrition, looking at both potential causes and consequences of the recent rise in body weight, as well as at evaluating ways to improve dietary choices. Second, she examines the use of genetic data in economics research. This interdisciplinary work includes policy-relevant applications, looking at genetic and environmental determinants of health and education, as well as methodological research using Mendelian randomization.
