Corinne Maurice aims to determine how bacteriophages – viruses that infect bacteria only – regulate the activity of the trillions of bacteria naturally present in the human gut.

As humans, we are walking microbial systems. Changes in the diversity and function of our microbial cells can have severe consequences for our health: obesity, diabetes, inflammatory bowel diseases, autism and allergies. Potentially, these conditions could be controlled or cured if we could regulate the metabolism of our gut bacteria.

Maurice pioneered the use of single cell tools and approaches developed in environmental microbiology and ecology to understand how bacteria respond to environmental changes and interact with their viral predators in the human gut. She demonstrated that common therapeutic drugs could rapidly alter bacterial activity – a  possible explanation for different side effects to the same therapeutic treatments. Her lab is currently taking these approaches further, to link bacterial diversity to specific functions and explore how phage infection changes these patterns.
