Biography

Tyler Brown is an infectious disease physician, epidemiologist, and Assistant Professor in the Section of Infectious Diseases. His scientific work uses phylogenomics, population genetics, and mathematical modeling to understand how microbial evolution, human host mobility, and other factors shape the transmission and geographic dispersal of tuberculosis and other infectious diseases.
