Research Scientist

Dr. Peter G. Mason is a Research Scientist with Agriculture and Agri-Food Canada (AAFC) in Ottawa, Canada. The focus of his research is invasive alien species and classical biological control with particular emphasis on host-range assessment and non-target impacts of parasitoids. This research has been central to formulating a science-based response to a changing regulatory environment for biological control agents worldwide.
