Research Interest: Innate immunity

Description of research activities: The innate immune system discriminates between “non-infectious self” and “infectious non-self” by sensing “pathogen associated molecular patterns” (PAMPs) expressed by infectious microorganisms. Toll like receptors (TLR) expressed on immune cells recognize PAMPs. This interaction initiates a robust innate immune response that enables the host to control the pathogen’s initial spread and subsequently generate sterilizing adaptive immunity. My research interest focuses on TLR ligands and their therapeutic applications as vaccine adjuvants, immune stimulants and anti-cancer agents.
