Biography
Charles Knowles undertook his preclinical training at Cambridge University and then moved to the London Hospital Medical College , qualifying in 1992. He quickly progressed with a career in surgery, passing the FRCS examination ( London ) in 1996. Prior to specialist training, he undertook a considerable body of research based at Barts & the London , and funded by the Royal College of Surgeons of England . During this time, he was awarded the degree of PhD at the University of London entitled 'clinical and aetiological studies in slow transit constipation'. He continued to actively participate in research during Specialist Registrar training (General Surgery) in the North-East Thames Region in the role of Clinical Lecturer in Academic Surgery. After successfully completing the final Intercollegiate Specialty Boards Examination in General Surgery (sub-specialty: Colorectal) he entered the Specialist Register in 2005. In September 2006 he was appointed Senior Lecturer in Colorectal Surgery on the basis of a prestigious award from HEFCE partnered by Honorary Consultant appointments at Barts and the London and the Homerton University NHS Foundation Trusts. His main clinical interest is in the management of benign coloproctological conditions.
Research Activity
Main research interests are :
Neuromuscular pathological aspects of gastrointestinal motility disorders
The molecular basis of gut sensorimotor dysfunction, particularly in relation to visceral hypersensitivity and pain
The role of autoantibody-mediated disease in gut motility disorders
The role of clinical tests of colorectal physiology in guiding therapy
