Dr. Maurice is a Tier 1 Canada Research Chair in Gut Microbial Physiology and a CIFAR Azrieli Global Scholar. She has been working with a systems biology approach on microbial communities for over 10 years, in aquatic systems and in the human gut. She pioneered the use of single cell approaches to understand how gut bacteria respond to perturbations and interact with their viral predators (bacteriophages). She demonstrated that common therapeutic drugs can rapidly alter bacterial activity – a possible explanation for different side effects to the same therapeutic treatments. Her collaborative work determined how diet and infection can alter bacterial activity and diversity. At McGill University, her lab is currently taking these approaches further to characterize gut bacterial metabolism, and how to regulate this metabolism with bacteriophages to promote health.
