Professional Profile
Dr Karen Sheares obtained her BA (Hons) in Physiological Sciences in 1990 and continued at Oxford University Medical School graduating with the degree of BM BCh in 1993. She commenced postgraduate training and obtained her MA in 1995 and MRCP in 1996. Subsequently she started an innovative and unique specialist registrar training programme in Respiratory Medicine, Clinical Pharmacology and General Medicine in Addenbrooke’s Hospital and Papworth Hospital. During this time, she was awarded a British Heart Foundation research fellowship to investigate how low oxygen levels regulate the growth of pulmonary artery smooth muscle cells resulting in pulmonary hypertension. This culminated in a PhD from the University of Cambridge in 2005.
 
She was appointed as Respiratory Consultant at Papworth Hospital and Honorary Respiratory Consultant in Cambridge University Hospitals in 2006 and obtained FRCP in 2011. She is the Respiratory expert on the National Institute for Health and Care Excellence’s Venous Thromboembolic Diseases Guidelines and Quality Standards Groups. She is the Clinical Pharmacology representative on the Papworth Hospital Drugs and Therapeutics Committee. Her research interest is the pathogenesis of pulmonary vascular remodelling in pulmonary hypertension particularly in the thromboembolic group.
