Jill is Professor of General Practice and responsible for the RVC's Continuing Professional Development (CPD) programme including management of the RCVS Certificate of Advanced Veterinary Practice. She is also Director of Bachelor of Veterinary Medicine (BVetMed) course and chair of the RVC's Equality and Diversity Committee. She contributes to the RVC's teaching programme for veterinary students and veterinary nurses in the areas of small animal medicine, clinical reasoning and clinical pharmacology.

Jill is a graduate of the University of Sydney. She completed an internship at the University of Sydney, spent 18 months in full time private practice in Sydney then completed a residency in small animal medicine at the University of Guelph, Canada. She returned to Australia and completed a PhD entitled Neurochemistry of Hepatic Encephalopathy at The University of Sydney. She was a senior tutor and clinician in the Department of Veterinary Clinical Sciences at the Univerity of Sydney from 1987 and from 1990-2000 was a senior lecturer in the Department of Pharmacology. During this time she also worked in general and specialist veterinary practice and was a consultant for a veterinary clinical pathology lab. In 2000 she became the Director of the Veterinary Science Foundation at the University of Sydney.

Jill moved to the UK with her family in April 2001. From 2002 she was a veterinary clinician and lecturer at the Royal Veterinary College, London based at the college’s first opinion practice and was appointed a Fellow at Girton College, Cambridge where she tutored in pharmacology. She is currently Professor of General Practice, Director of Professional Development and Director of the BVetMed course at the Royal Veterinary College (RVC). She is actively involved in undergraduate teaching and CPD at the RVC in the areas of small animal medicine, clinical problem solving and clinical pharmacology.

Jill has published over 60 refereed papers in veterinary and medical journals and is the senior editor of Small Animal Clinical Pharmacology, the 2nd edition of which was published by Elsevier in 2008. She is also senior editor of Clinical Reasoning in Small Animal Practice published by Wiley-Blackwell in March 2015. She has lectured extensively around the world on clinical problem solving, small animal internal medicine and clinical pharmacology. Jill was co-chair of the Scientific Program Committee for the World Small Animal Veterinary Association Congress held in Sydney in 2007 and is the coordinator of the small animal main clinical CPD streams at The London Vet Show. She is also the regional coordinator for South East Asia on the World Small Animal Veterinary Association Continuing Education Committee. To keep in touch with the realities of private general practice she consults at a local veterinary practice and at the RVC’s first opinion practice, the Beaumont Sainsbury Animal Hospital.

Since graduation, I have practised and taught small animal medicine and clinical pharmacology to veterinary undergraduates in academic institutions on three continents as well as to practising veterinarians in many countries and veterinary nurses at the RVC. I have held teaching positions at the University of Sydney (small animal medicine, pharmacology), University College Dublin (pharmacology), Girton College, University of Cambridge (pharmacology) and the Royal Veterinary College (small animal medicine, clinical pharmacology, veterinary nursing).  I have also played a seminal role in the development of continuing education for veterinary surgeons around the world for many years in almost every format imaginable – large lectures, small group seminars, distance learning and a range of different online platforms – including tutor moderated e-learning courses and webinars.

Throughout my career, regardless of my academic position, I have worked in veterinary practice at both generalist and specialist level. At the heart of my teaching philosophy is “practice what you preach”: I should never presume to teach something I do not practice. The principles that underlie my teaching, both undergraduate and postgraduate, are centred on a desire to transform the student’s or veterinarian’s understanding and thus generate fundamental changes in his or her everyday practice. I passionately believe that veterinary education should not only build the knowledge base and technical skills of students and veterinarians but also enhance their thinking and problem-solving skills. Educational delivery in whatever format should be inspiring and transforming.
