The focus of my laboratory is on elucidating the relationship between diet, the microbiome and colon cancer etiology. Our goal is to 1) delineate the dietary factors that modify the microbiome and its function, 2) develop microbial multi-omic classifiers that improve stratification of patients for colon cancer treatment, and 3) identify key functional pathways and mechanisms of the microbiota-host communication, including nucleic acid sensing cell receptors that control inflammation. Ultimately, our goal is to discover microbial and metabolic targets for the development of clinical tools to improve the treatment and reduce mortality from colon cancer.
