Dr. Jelinski received his DVM from the Western College of Veterinary Medicine in 1985. Shortly after graduation he established a mixed animal practice in Moosomin, Saskatchewan, which he owned and operated for seven years. In 1992 he returned to the WCVM to complete a MSc. degree in epidemiology, his research topic involved describing the epidemiology of fatal abomasal ulcers in young unweaned beef calves.
Following his MSc, Dr. Jelinski embarked upon a career in the Canadian veterinary pharmaceutical industry, starting as the Manager of Regulatory Affairs and Product Development with Hoechst Roussel Vet. After a number of successive positions within the industry he ended his pharmaceutical career as General Manager for MetaMorphix Canada Inc., an early stage biotechnology company.
In January 2006 he joined the WCVM as the Alberta Chair in Beef Cattle Health and Production Medicine.
Dr. Jelinski has a longstanding interest in the changing demographics of the veterinary profession in Western Canada. Since assuming the Beef Chair position he and Dr. John Campbell have been actively investigating the factors that influence veterinarians' choices of a career path. Dr. Jelinski is also involved in investigating how much time veterinarians are engaged in veterinary medicine, how much time they spend on particular species and how many western Canadian clinics are currently seeking new veterinary associates.
In addition, Drs. Campbell and Jelinski are also involved in studying the ecology and epidemiology of Mycoplasma bovis in the feedlot. M. bovis is the causative agent of the chronic pneumonia and polyarthritis syndrome (CPPS) associated with high-risk fall-placed beef cattle.
