Biography
Sarah Barrett is an Assistant Professor in Radiation Therapy at Trinity College Dublin, where she has been a faculty member since October 2015. A graduate of Trinity College, she brings almost a decade of clinical experience to her academic role, including work at Clinical Specialist level. She completed her MSc in Treatment Planning in 2014 and recently earned her PhD, which focused on mathematical modelling in non-small cell lung cancer (NSCLC) to support personalised radiotherapy strategies. As Course Director of the BSc Radiation Therapy programme, Sarah is committed to delivering a curriculum that emphasises evidence-based practice, clinical excellence, and person-centred care. Her teaching is informed by her strong clinical background and ongoing research. Her research interests include lung cancer, adaptive radiation therapy, stereotactic ablative radiation therapy (SABR), and the use of radiation therapy in benign disease. Her work focuses on the personalisation of treatment through quantitative modelling, aiming to improve outcomes and optimise care pathways. She is an active member of the European Society for Radiotherapy and Oncology (ESTRO), contributing to the lung cancer focus group and is faculty on the SABR teaching courses that support professional development and innovation in radiation oncology across Europe. Her dual expertise in academic and clinical settings enables her to foster interdisciplinary collaboration and lead impactful initiatives.
