Oliver was until recently a member of the Small Animal Internal Medicine team within the Queen Mother Hospital for Animals (QMHA), seeing dogs and cats with all manner of medical problems.
He has now moved to the School of Veterinary Medicine at the University of Pennsylvania, where is the Henry and Corinne R Bower Professor of Medicine and Chair of the Department of Clinical Sciences & Advanced Medicine.
His particular clinical interests include gastrointestinal and immune-mediated disease. Oliver has contributed chapters on immune-mediated disease and gastrointestinal immunology to two widely read textbooks in the field.
Oliver is also involved in the teaching and supervision of both Junior and Senior Clinical Training Scholars (Interns and Residents) in the QMHA and now the Ryan Hospital for Companion Animals, having contributed to the training of over 40 Junior and over 55 Senior Clinical Training Scholars over the years.
Oliver was a regular contributor to the RVC's schools outreach programme, including the 'RVC on Tour' and the BSc (Bioveterinary Sciences) Open Day for school children. He also volunteers for British Society for Immunology public engagement activities (e.g. The Secret Life of Snot at the Big Bang Fair, ExCel Centre, London). He passionately believes in the importance of clear communication of scientific issues to the greater public and his research was featured in a recent podcast ('RVC 50') and RVC Annual Research Highlights event. He has lectured to veterinarians and veterinary nurses in the UK, USA and Asia – both general practitioners and specialists.
Oliver's paper on the haematological phenotypes of different dog breeds, published in PLOS ONE, has been featured in a recent Press Release - RVC study provides large-scale analysis of blood cells in dog breeds. This work not only has immediate implications for canine medical practice, but also has far-reaching ramifications for our understanding of the genetic determinants of blood cells in health.
