Biography: 

S茅bastien P. Faucher graduated from Universit茅 de Montr茅al in Microbiology and Immunology in 2003. He obtained his PhD in Microbiology and Immunology from Universit茅 de Montr茅al in 2007. The subject of his thesis was the identification of virulence genes in Salmonella typhi. Between 2007 and 2010 he was a postdoctoral fellow at Columbia University in New York City. He conducted research on Legionella pneumophila under the supervision of Howard Shuman. He returned to Montr茅al in June 2010 for a postdoctoral fellowship with Dr. Philippe Gros at 涩里番. During this time, he studied the genetic determinants involved in cerebral malaria. He joined the Faculty of Agricultural and Environmental Sciences in July 2011. His research teams focus on the genetic, evolution, and ecology of water-borne pathogens. He has published more than 65 peer-reviewed research papers and supervised 16 graduate students.

Research areas: 
Agricultural and Soil Sciences
Ecology and Biodiversity
Environmental Health and Toxicology
Current research: 

Genetics of evolution of water-borne pathogens water-borne pathogens. Prof. Faucher鈥檚 team members are using adaptive laboratory experiments to understand how water-borne pathogens adapts to environmental stressors and disinfectant and become more difficult to control. Microbial ecology of water systems. Engineered water systems harbors a complex microbiota that may promotes or, to the contrary, inhibits growth of water-borne pathogens. Prof. Faucher鈥檚 team members used metagenomics and 3D-printing to understand the interactions between microbes and discover novel mechanisms of competition. Bacteriophages are also studied with the aim of developing novel biocontrol strategies. Citizen science. With the help of citizen researchers Prof. Faucher鈥檚 team members are identifying risk factors for water-borne pathogens and finding novel action point.

Areas of interest: 

My research group focus on understanding how water-borne pathogens grows and survive in water systems. The aim is to find novel sustainable strategies to control them and limit their transmission to humans.
