Cathal Walsh is the Professor of Biostatistics in the School of Medicine at Trinity College Dublin, having previously held the Chair of Statistics at the University of Limerick. His work in Medical applications in the last decade was supported by a Health Research Board Research Leader award in Health Decision Science. He has held visiting appointments in Bayesian groups in Australia (at Queensland University of Technology) and in the Harvard School of Public Health in the United States. He is a Fellow of the Royal Statistical Society, having served on Council and as Honorary Officer for Sections and Local Groups. With others in the Society he has helped develop the African Institute for Mathematical Sciences M.Sc. in Statistics and Data Science, visiting and lecturing on that programme. His research interests are in evidence synthesis and disease modelling, and he was part of the Irish Epidemiological Modelling Advisory Group, working within the Health Protection Surveillance Centre during the COVID-19 pandemic. He has been an advisor to the National Centre for Pharmacoeconomics on statistical methodology for Health Technology Assessment for over 15 years, and has been the trial statistician for clinical trials in stroke, depression and activity interventions.
