Fergal O'Donoghue initially trained at the National University of Ireland in Dublin before moving to Australia in 1993. He trained as a Respiratory Physician at Sir Charles Gairdner Hospital in Perth and Repatriation General Hospital in Adelaide where he completed further subspecialty training in sleep medicine and a PhD on noninvasive ventilatory support (BiPAP) in severe COPD. He moved to Melbourne in 2001 and took up a position at Austin Health and Warringal Private Hospital. He has continued an active research career and holds a number of NHMRC grants, and is a lecturer at Melbourne University. He has served on national committees in the respiratory and sleep specialty societies, and at the RACP, with a particular interest in specialist training and laboratory accreditation. His major subspecialty interest remains in sleep medicine and noninvasive ventilatory support but he continues to practice in all areas of respiratory medicine and of recent years has been increasingly involved in lung cancer diagnosis and management.
