I trained in medicine at University College, London, and received my MB, BS degree in 1980. Following this I trained in general medicine and then clinical oncology in the UK. In 1991, I was appointed as Staff Radiation Oncologist at Princess Margaret Hospital, Toronto and Associate Professor at the University of Toronto.
In 1999 I returned to the UK, to become a Consultant in Clinical Oncology, specialising in Urological Cancers, at Weston Park Hospital, Sheffield. Subsequently I also took on the roles of Clinical Director for Radiation Services and Cancer Lead Clinician for Sheffield Teaching Hospitals NHSFT, and Lead Clinician for the North Trent Cancer Network. Between 2012 and 2017 I was the Medical Director at the Clatterbridge Cancer Centre, Wirral, before stepping down in 2017 and retiring from clinical medicine in March 2019.
I was the Lead Clinician for the NICE Prostate Cancer Guideline (2014), the National Clinical Lead for Radiotherapy for NHS Improvement/National Cancer Action Team (2002-13), and was Chair of the Radiotherapy Clinical Reference Group (NHS England). I am currently a trustee of the Council of the Royal College of Radiologists.
