Oliver is the Henry and Corrine R Bower Professor of Medicine and Chair of the Department of Clinical Sciences & Advanced Medicine at the School of Veterinary Medicine at the University of Pennsylvania.
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 interns and residents at the Ryan Hospital for Companion Animals, having contributed to the training of 43 interns and 58 residents over the years at his previous academic home, the Royal Veterinary College.
Oliver passionately believes in the importance of clear communication of scientific issues to the greater public. He has participated in outreach programs for school children and volunteered for the British Society for Immunology public engagement activities (e.g. The Secret Life of Snot at the Big Bang Fair, ExCel Centre, London). He has lectured to veterinarians and veterinary nurses in the UK, USA and Asia – both general practitioners and specialists.
Oliver's paper on the hematological phenotypes of different dog breeds, published in PLOS ONE, has been featured in a 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. This paper has been downloaded over 50 times from Oliver's ResearchGate page.
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.
