He chaired the Advisory Group to the NHMRC National Organ Donation Collaborative (2006-2008); and the Working Group which wrote the National Protocol for Donation after Cardiac Death.Dr O'Callaghan graduated from the Royal College of Surgeons in Ireland, after which he undertook postgraduate training in anaesthesia in Ireland and the United Kingdom. He subsequently trained in intensive care medicine in Australia, gaining fellowship of the College of Intensive Care Medicine in 1997. He became interested in the challenges of facilitating organ donation and the interface with transplanation medicine while working in the Institute of Liver Studies, Kings College Hospital, London.Dr O'Callaghan's career is marked by extensive experience in clinical intensive care medicine including heart, liver and renal transplantation both pre and post-transplant surgery in Australia, Ireland and the United Kingdom; adult and paediatric cardiac surgery programs; trauma and aeromedical retrieval services; ethics, policy development and implementation and clinical practice improvement.His clinical experience in critical care and anaesthesia has been in tertiary referral teaching centres which manage high acuity complex caseloads with high levels of occupancy and activity. Dr O'Callaghan has consequently developed a focus on the translation of sound evidence based practice into effective patterns of clinical service delivery focused on the needs of patients and families. The tools for delivering high quality care have become the focus of his research interests.He currently serves on the South Australian Clinical Senate (December 2011 -) and is the Inaugural Chair of the ANZICS Education Committee (2011 -).
