Our research is reflective of health questions at both population and community levels, with particular emphasis on lifestyle issues and how these affect people's health. Illicit drugs and alcohol use, childhood and adult obesity, cancer prevention, chronic disease and multi- morbidity along with genetic epidemiology and gene-environment interaction, all form part of our research agenda. Staff members are involved in the Growing up in Ireland (GUI) study, which provides a rich seam of data for research.
