Research / Scholarly Activities

Dr. Chalhoub's current research includes nephrology/urology and interventional medicine.


Serge Chalhoub graduated from Bishop’s with a BSc. (Honours) in Biology in 1999. He then enrolled in the Doctor of Veterinary Medicine (DVM) program at the Faculté de médecine vétérinaire (FMV) of the Université de Montréal and completed the 5-year program in 2004. Serge followed this with a one-year rotating small animal clinical internship at the same institution. 

After working for two years as a general practitioner and emergency veterinarian in Montreal, Serge pursued a residency in small animal internal medicine at the Animal Medical Center (AMC) in New York City. Once his residency completed in 2009 he stayed on at the AMC as their first renal/hemodialysis fellow and then as a staff doctor. 

Dr. Chalhoub has been a faculty member at the University of Calgary’s Faculty of Veterinary Medicine (UCVM) since 2012 and currently holds the rank of Associate Professor (Teaching). He was the recipient of the 2021 and 2013 Canadian Veterinary Medical Association’s Teacher of the Year Award, the 2015 University of Calgary Team Teacher of the Year Award, and the 2017 Carl J. Norden Distinguished Teacher Award (considered the most prestigious teaching award for a veterinary faculty member in North America). Serge is the coordinator of a community outreach-service learning program (UCVM-CUPS Pet Health Clinic) for disadvantaged Calgarians. He has authored and co-authored numerous scientific articles and book chapters on veterinary point of care ultrasound, renal and urinary medicine, and lectures around the world on these topics. He is a member of the National Issues Committee (NIC) of the CVMA and a Council Member for the Alberta Veterinary Medical Association.
