Dr. Sionagh Smooth received her veterinary degree from the University of Glasgow in 1990. After four years in Yorkshire-based mixed veterinary practice, she undertook a PhD within the Department of Veterinary Pathology at the University of Edinburgh, focusing on epidemiological and pathological aspects of proliferative enteropathy in pigs. Following a three-year residency at the University of Pennsylvania in Philadelphia, Sionagh became a Diplomate of the ACVP in 2000. She remained in Philadelphia for an additional year as a lecturer, then spent two years with Idexx Laboratories in the UK.  In 2005, after a two-year spell as Assistant Professor of Veterinary Pathology at the University of Tennessee’s College of Veterinary Medicine, Sionagh joined the Royal (Dick) School of Veterinary Studies, where she was Senior Lecturer of Veterinary Pathology and, latterly, Head of Pathology.  In 2019 she spent a 6-month sabbatical in Australia, working with the New South Wales State Veterinary Diagnostic Laboratory (Elizabeth MacArthur Agricultural Institute).  She left the University of Edinburgh in 2021 to take a position as a veterinary pathologist with Finn Pathologists, a commercial diagnostic laboratory based in Norfolk, UK.
