Faculty Information


Dr. Seshadri's research focuses on the human immune response to Mycobacterium tuberculosis, the bacteria responsible for tuberculosis. By better understanding what factors are responsible for protective immunity, he hopes to contribute to ongoing efforts to develop an effective vaccine. Specifically, his work addresses two questions:

  • What is the role of T-cells that respond to lipids and small molecules produced by bacteria?
  • Why do some people fail to convert their tuberculin skin tests despite frequent and close contact with tuberculosis patients?
