Dr Páraic Ó Súilleabháin is a Lecturer in Psychology at the Department of Psychology, University of Limerick, Ireland. Páraic also serves as the Research Coordinator on the Doctoral Programme in Clinical Psychology. Páraic’s research is primarily focused on the biobehavioural processes underlying disease and mortality. Páraic examines the associations between biobehavioural factors (such as personality traits, loneliness, stress) on the accumulative lifespan development and progression of disease (such as cardiovascular disease), and mortality trajectories across the lifespan. While utilising several approaches, including both longitudinal and experimental methods, Páraic is interested in the identification of individual differences involved in health processes. He has received several awards, and both national and international recognition for his research.
