Harut   Avsaroglu DVM, PhD, DipECLAM

Director of Animal Resources

Dr. Harut Avsaroglu graduated (DVM) from the Faculty of Veterinary Medicine of Utrecht University, The Netherlands in 1999. Following two years of private veterinary practice he returned to Utrecht University to pursue a PhD (2001-2004) on laboratory animal anesthesia. During this time, he was also locum veterinarian for the Central Laboratory Animal Institute (CLAI) at Utrecht University. In 2004, Dr. Avsaroglu became manager of veterinary affairs and started a residency in laboratory animal medicine at CLAI. In 2007, he completed the Post-Graduate Vocational Course on Laboratory Animal Science. From 2008, he was seconded as clinical veterinarian at the Animal Research Institute AMC (ARIA) in Amsterdam and at TNO Triskelion (2009-2011) in Zeist.  Dr. Avsaroglu achieved board certification by the European College of Laboratory Animal Medicine in 2010. The following year he left CLAI and was employed as clinical veterinary manager at ARIA. In 2016, he joined Ross University School of Veterinary Medicine (Ross), St Kitts, West Indies, as both Director of Animal Resources and Attending Veterinarian.

Dr. Avsaroglu provides leadership and oversight of the Institutional Animal Care and Use Program at Ross and currently leads and manages the full accreditation process for AAALAC International. He also contributes to the DVM/postgraduate teaching program in the areas of laboratory animal medicine and science and participates in individual and collaborative research under the One Health research centers at Ross. He is an active member of several university committees including the Institutional Animal Care and Use Committee, the Postgraduate and Research Committee and the Business Operations Committee and serves as faculty advisor for our student chapter of the American Society for Laboratory Animal Practitioners (ASLAP). In 2017, Dr. Avsaroglu was elected to serve as the World Veterinary Association’s (WVA) Councillor for International Discipline-Centred Organizations.
