Tom studies the functional and clinical significance of human variation in the innate immune system and its regulation of susceptibility to tuberculosis and other infections. His laboratory defines and characterizes the cellular function of genetic polymorphisms in innate immune response genes and the mechanisms of how they regulate susceptibility to human infection with an overall goal of elucidating novel therapeutic strategies.

Research Projects

Current research projects include examination of the immune response to Mycobacteria. These studies are focused on understanding why individuals are resistance to M. tuberculosis infection, what regulates the response to vaccination, and studying why some individuals get more severe forms of tuberculosis (e.g. TB meningitis). All of the projects the studies involve examination of the human immune response with a mixture of genetic and cellular techniques to compare immune responses in different populations. Cellular studies include manipulation of gene expression with gene editing techniques and the study of innate immune responses to M. tuberculosis infection in monocytes and macrophages.
