Justin Stebbing is a member of the Royal College of Physicians, American Board of Internal Medicine and the Royal College of Pathologists. Originally, Justin trained in medicine at Trinity College Oxford (Oxford, UK), obtaining a triple first class degree. After completion of junior doctor posts in Oxford, he undertook a residency (junior doctor) training at The Johns Hopkins Hospital (MD, USA), before returning to London to continue his training in oncology at The Royal Marsden. Justin then undertook a PhD, funded by the medical research council, investigating the interplay between the immune system and cancer. Specifically, the role of heat shock proteins in tumorigenesis was examined, leading to the development of a cancer vaccine that is currently in clinical trials. Justin has published over 200 papers and book chapters, in journals such as the Lancet, New England Journal, Blood, the Journal of Clinical Oncology and Annals of Internal Medicine, the majority as first or last author. They mainly focus on early and late stage trials of new drugs, mechanisms of disease and prognostic indicators. He is on the editorial board of a number of journals and regularly serves as a referee. Justin's main focus is now in breast cancer, and helping patients with early and late stage disease get better.
