Biography

Brent L. Williams is an Assistant Professor of Epidemiology at the Mailman School of Public Health, Columbia University. His research focuses on the role of the microbiome in human health and disease, particularly how complex microbial communities in the human body can maintain health through mechanisms related to digestion, metabolism, immunity, and protection against infections. Dr. Williams employs advanced sequencing and computational techniques to explore the disruptions in human symbiotic microbial consortia that contribute to various pathophysiological states. His studies cover a broad range of topics, including the microbiome's role in neurodevelopment and autism, the influence of microbial metabolites on epigenetic changes relating to colorectal cancer, and the identification of vaginal microbial communities that may contribute to inflammation and adverse pregnancy outcomes, including HIV risk. He is also interested in the evolutionary factors that influence microbiome structure in relation to our closest primate relatives.
