Biography summary
Dr. Luis Afonso is a fish physiologist with an interest in fish health (stress) and reproduction. Luis completed an MSc degree at the Federal University of Rio Grande do Sul (Brazil – 1992) on sex reversal in fish, and a PhD at the University of British Columbia (Canada - 1997) on reproductive endocrinology of Pacific salmon.
After his PhD, Luis took on an associate professor position at the Federal University of Rio Grande do Sul (1997-2000), and he worked closely with the aquaculture industry on research and development projects aimed at producing monosex population of Nile tilapia.
Luis returned to Canada in 2000 to take on a Visiting Scientist position with the Department of Fisheries and Oceans Canada to work on the effects of environmental pollutants during sexual development in fish. In 2001 he joined the National Research Council of Canada, Institute for Marine Biosciences (Halifax-Canada) where he developed a research program on stress in fish. From 2009-2012, Luis took up a Senior Research position with the BC Centre for Aquatic Health Sciences (Campbell River-Canada) to work on fish health.
For the past 15 years, Luis has been working closely not only with his colleagues at academia but also with the private sector, as he thinks that an interdisciplinary team based approach is vital for understanding, maintaining, and advancing our knowledge in life sciences.
