The Institute of Public Health in Ireland (IPH) promotes cooperation for public health on the island of Ireland. The Bamford Centre for Mental Health and Wellbeing at Ulster University and the Institute of Public Health in Ireland are working together to identify the most effective interventions to address loneliness among older people. IPH invites applications for this fixed-term post of Public Health Interventions Officer – Loneliness. This post will be based between both organisations and aims to help inform the identification and design of effective Public Health interventions to address loneliness and to effectively measure the outcomes of these interventions.
