Research Scientist

Dr. Pierre Lacasse has obtained a Ph.D. in Animal Science from McGill University in 1993.

In 1994, he did a postdoc at Ruakura Agricultural Research Centre in Hamilton, New Zealand; where he investigated the relationship between mammary gland blood flow and milk production.

Since 1995, he is a research scientist in Biology of lactation for Agriculture and Agri-Food Canada at the Sherbrooke Research and Development Centre in Sherbrooke, Québec. His current research program focus on the biological control of lactation persistency, factors controlling milk synthesis, effect of dairy cow management on productivity and susceptibility to diseases and the development of new tools to fight mastitis.

He is one of the founding member and leaders of the Canadian Bovine Mastitis and Milk Quality Research Network.
