Trillions of bacteria live in our gut. This community of microbes is called the gut microbiome. The gut microbiome is a rich source of small molecules. While the majority of gut microbiome-derived molecules are beneficial to our health, many can be harmful. Diseases such as inflammatory bowel disease and colorectal cancer are associated with changes in the gut microbiome. However, little is known how these changes alter the production of small molecules and if these molecules play any role in these diseases. Therefore, my research goal is to identify gut microbiome-derived molecules that are associated with such diseases, then to uncover the their role in disease development.
