THOMAS M. DONNELLY received degrees in veterinary medicine and pathology from the University of Sydney, Australia, and then moved to The Rockefeller University, New York, to study comparative medicine and pathology, becoming a Diplomate of the American College of Laboratory Animal Medicine. Besides providing biomedical research services to universities and pharmaceutical companies, Tom also enjoys seeing exotic pets and is a Diplomate of the American Board of Veterinary Practitioners and the European College of Zoological Medicine. He was a member of the Avian & Exotic Pet Services at Animal Medical Center in New York and has an Adjunct Faculty appointment at Tufts Veterinary School in Massachusetts in the Zoological Companion Animal Medicine service. Tom is currently working at the French National Veterinary School of Alfort, where he is a research professor and co-service head of the Exotic Animal Service. He is a consultant on the Veterinary Information Network (VIN) and is the author of over two-hundred scientific and clinical publications, including chapters in “Ferrets, Rabbits and Rodents: Clinical Medicine Surgery” and is the co-editor of “Veterinary Clinical Advisor: Birds and Exotic Pets.” Tom is allergic to most mammals. Although his veterinary medicine career and allergies collide, he is fortunate in finding the challenges and diversity of working with researchers, exotic pets and their often equally unusual owners constantly gratifying.
