Gayle graduated from the University of Cambridge with a distinction in 2002. She then initially completed an internship in equine studies and then a residency in large animal internal medicine and critical care at the Royal Veterinary College. Her main areas of interest were analgesia and anaesthesia of large animals, cardiology, gastro-intestinal disease and ultrasonography. After a stint as a clinical instructor in anaesthesia and Lecturer in Equine Medicine at the Royal Veterinary College, Gayle moved to the University of Nottingham to complete a PhD funded by the Horserace Betting Levy Board investigating aortic valve prolapse in the horse. In 2007 Dr Hallowell was also made Special Lecturer in Large Animal Internal Medicine and Critical Care at the University of Nottingham and contributed to design and delivery of various areas of the curriculum. Since 2010, she has had a tenured position at the University where she is currently Professor in Veterinary Internal Medicine and Critical Care. She is rotation lead for the Defence Animal Centre, Equine Skills and Bransby and module lead for emergency and critical care teaching. Recent qualification acquisitions include Principal Fellow of the Higher Education Academy, RCVS Specialist in Equine Internal Medicine and Emergency and Critical Care and Associate Diplomate of the European College of Veterinary Diagnostic Imaging.
Clinical and research interests:
In addition to Dr Hallowell's clinical and research interest in cardiology, gastro-enterology and ultrasonography, she is interested in large animal critical care, particularly relating to fluid therapy and acid-base. Other clinical areas of specific interest include large animal and equine ophthalmology, neurology, analgesia and anaesthesia.
