Overview

Karen is an Associate Professor in Musculoskeletal Imaging at the University of Exeter and Head of Medical Imaging. She developed an interest in osteoporosis in her first job as a Nuclear Medicine Radiographer. She went on to undertake a PhD in this area at King’s College London, with internationally renowned groups in osteoporosis and twin research, based at Guy’s and St Thomas’ Hospitals.  During her post-doctoral positions, she honed her educational skills teaching medical students and went on to a lectureship at the University of Exeter in 2004. She now combines teaching and research across two colleges, teaching undergraduate radiographers and clinical research to senior practitioners on the Doctorate in Clinical Research. Her primary research interest continues to be bone health and osteoporosis.  More recently, she is developing expertise in other pathologies such as diabetes and particularly how these relate to bone health and fracture risk. Karen is committed to research-led teaching, where she uses her experience and expertise to inspire the next generation of radiographers.
