Tim Williams is available for consultancy.

Office Phone: 01223 337621


Tim qualified from the University of Cambridge in 2007, and following a year working in small animal practice in west London, he undertook a PhD in the Feline Research Group at the Royal Veterinary College, London under the supervision of Professor Jonathan Elliott and Professor Harriet Syme. His research focused on feline geriatric medicine and, in particular, the effect of hyperthyroidism on renal function in cats. He received the Society for Comparative Endocrinology award for “Excellence in the Advancement in Veterinary Endocrinology” in 2011 and 2015. Tim joined the department in 2012 as Senior Clinical Training Scholar in Veterinary Clinical Pathology and subsequently became Lecturer in Clinical Pathology in September 2015. He is a Fellow of the Royal College of Pathologists and a Diplomate of the European College of Veterinary Clinical Pathology.

Tim is currently the Chair of the BSAVA Metropolitan regional committee and is Treasurer of the European Society of Veterinary Clinical Pathology.
