Paul A. White obtained his PhD in biology from McGill University (Montreal) in 1996; his research investigated the sources and fate of mutagens and carcinogens in the St. Lawrence river system. He conducted post-doctoral research at USEPA facilities in Rhode Island and North Carolina; investigating the mutagenic hazards of municipal wastewaters. He joined Health Canada in 1999, and is currently a senior research scientist and leader of the genetic toxicology lab group in the Mechanistic Studies Division of the Environmental Health Science and Research Bureau. In 2002 he appointed Professor of Chemical and Environmental Toxicology in the Department of Biology of the University of Ottawa. His current work investigates the mutagenic and carcinogenic activity of complex mixtures, the design and validation of in vitro and in vivo tools for genetic toxicity assessment, the use of molecular biomarkers for mutagen exposure assessment, and the development of quantitative methods for interpretation of genetic toxicity dose-response data. He has published over 100 peer-reviewed scientific papers, and his work has been cited over 4000 times. From 2007 to 2011 he served as the editor-in-chief of Environmental and Molecular Mutagenesis; he currently serves on the editorial boards of Environmental and Molecular Mutagenesis, Mutation Research Reviews and Food and Chemical Toxicology. His research has been recognized by scientific leadership and research excellence awards from the Deputy Minister of Health of the Government of Canada, and the Governor General of Canada’s Gold Medal. He is the current president of the International Association of Environmental Mutagenesis and Genomics Societies (IAEMGS), and the program chair for the 13th International Conference on Environmental Mutagens (ICEM), which will be held in Ottawa, Canada in September 2021.
