In 2013, Dr Ridge was appointed as a consultant radiologist at Mater Misericordiae University Hospital in Dublin and joined the Trust in July 2017. 

Areas of expertise

Dr Ridge is strongly committed to cardiothoracic, oncologic imaging and interventional radiology. In her role as a consultant radiologist at the Trust, she has clinical expertise in cardiothoracic imaging and lung tumour ablation.  Her research work in these fields was acknowledged with a Radiologic Society of North America Roentgen Fellow Research Award in 2013.

Her research interests include lung cancer diagnosis and treatment, cardiac and pulmonary embolism imaging.
