Jane A. Foster, Ph.D., is an associate professor in the Department of Psychiatry and Behavioral Neurosciences at McMaster University and a member of the Brain-Body Institute, St. Joseph’s Healthcare in Ontario, Canada. Following completion of her doctoral work at the University of Toronto, she was a postdoctoral fellow at Henry Ford Hospital in Detroit, and then a research fellow at the National Institute of Mental Health. Foster joined the McMaster faculty in 2003, where her research program investigates the brain-gut axis. Recent work from their group has established a link between gut microbiota and behavior. Ongoing work investigates the importance of gut microbiota and immune-brain crosstalk to normal brain development, and to the risk of psychiatric disorders, and eventually, how best to therapeutically target microbiota and the immune system in disease.
