I spent 30 years as a consultant histopathologist at Addenbrooke's Hospital, Cambridge, for most of this period as the Director of Histopathology, and for five years as the Director of Pathology. My special interest was in the pathology of liver disease and especially in the pathology of liver transplantation. Addenbrooke's Hospital, under Professor Sir Roy Calne of the University of Cambridge, was one of the pioneer kidney and liver transplant centres in the world. I retired from the National Health Service in 2002.
Although my main employer was the NHS, I was also an Associate Lecturer in the University of Cambridge. I have been a Fellow of St John's College, Cambridge, since 1976, where as a College Lecturer and Director of Studies in Pathology I was responsible for the teaching of pathology to medical and natural sciences undergraduates. I was also Director of Studies in Clinical Medicine, but have now retired from these positions.
