Prof. St-Hilaire received her veterinary degree from the University of Prince Edward Island (UPEI), Canada, in 1994. She then completed her MSc and PhD in veterinary epidemiology at the University of Saskatchewan and the University of Guelph, respectively. She also holds an MBA from UPEI.

Before joining City University of Hong Kong, she was a Canada Research Chair at the Atlantic Veterinary College, Prince Edward Island, Canada. Prior to that appointment, she was an associate professor at Idaho State University in the U.S. She has also worked for a number of government agencies including the Department of Fisheries and Oceans in Canada, the Centre for Environment, Fisheries & Aquaculture Science in the UK, and the Chilean Government.

Most of her classroom teaching has been on aquatic animal health and epidemiology. She has mentored 24 undergraduates and 18 graduate students, as well as 4 post-doctoral researchers.

Prof. St-Hilaire’s research over the last 20 years has covered topics ranging from fish nutrition to infectious disease control and surveillance. She has been involved in a number of fish disease outbreak investigations ranging from viral to parasitic in origin in both wild and farmed animal populations. Most recently, she has been evaluating area level management strategies in aquaculture industries and treatment efficacy of different pharmaceutical products against parasitic and bacterial diseases of fish. She has over 70 peer-reviewed publications.
