Research Interests

Dr. Paul Virkler is a 1998 graduate of the College of Veterinary Medicine at Cornell and a 1995 graduate of the College of Agriculture and Life Sciences at Cornell. After graduation he began work at Attica Veterinary Associates in Western NY as a cattle veterinarian doing routine preventative and sick animal veterinary work. He took a six month sabbatical leave to Ragusa, Italy on the island of Sicily where he worked on a milk quality and mastitis project with the goal of improving the quality of a local cheese produced on individual farms. Upon returning to Attica Veterinary Associates he joined the partnership and spent the next six years helping individual farms improve the health of their herds. In 2005, he took a technical service veterinarian position with DeLaval covering the United States, Mexico, and Canada. In this role, he was focused on exploring the ways to improve the interaction between milking equipment and cows through research, training, and product development. Since 2008, he has been a faculty member in the Veterinary Support Services unit at the Animal Health Diagnostic Center in the College of Veterinary Medicine at Cornell University. In this position, he assists federal, state, and private veterinarians across the United States in disease investigations involving all species, and teaches veterinary students in the field of diagnostic sciences.
