Brent L. Williams, PhD, is an Assistant Professor in the Department of Clinical Pathology and Cell Biology at Columbia University. Dr. William’s research focuses on the role of the microbiome in human health and disease. The human body harbors ten times as many microbial cells as human cells, and these complex, symbiotic microbial communities play a fundamental physiological role in maintaining human health through various mechanisms relating to digestion, metabolism, immunity, protection from infections, and development. Dr. Williams applies state-of-the-art sequencing and computational techniques to gain mechanistic insights into how disruption of the human symbiotic microbial consortium contributes to disturbed host-microbe relationships and development of pathophysiological states. His research relating to these topics is broad in scope ranging from investigations into the role of the microbiome in neurodevelopment and autism; mechanisms by which microbial metabolites influence epigenetic changes in colorectal cancer; identification of vaginal microbial community states that contribute to inflammation, adverse pregnancy outcomes and HIV risk; and evolutionary factors governing the structure of our microbiome through investigation of our closest living primate relatives.
