Brief biography

I grew up in Montreal and completed my first degree at McGill (BSc Honours) followed by post-graduate studies at Memorial University of Newfoundland (MSc) and the University of British Columbia (PhD), and then a NATO Science Fellowship in England. I have been at UNB since 1989, where my research program in fish physiology emphasizes the application of scientific knowledge and training to advancing aquaculture. I have supervised the research of approximately 50 graduate students (mostly at UNB), many of whom have gone on to careers in aquaculture. I am on the editorial advisory boards of the journals Aquaculture and Acta Ichthyologica et Piscatoria and am a past Associate Editor of the North American Journal of Aquaculture. I have served twice as President of the Aquaculture Association of Canada and have been a science advisor to the United Nations (WHO and FAO), US government (FDA), and Canadian government (DFO), mostly on issues related to risk assessment/management of genetically modified fish. In addition to my research and teaching commitments at UNB, I am also Director of Animal Care.
