Research Interest: Innate immunity


Description of research activities: Our group is conducting research on mechanisms of innate immune sensing. One major research focus is on strategies to improve the delivery and boost the activity of pattern recognition receptor ligands that would be of interest as vaccine adjuvants. Particularly, we have been testing such adjuvants in murine tumor models and in Leishmaniasis. Another research focus of our lab is to employ Leishmania or bacteria-derived extracellular vesicles as vaccine antigens and/or immunomodulatory agents. Our lab is also interested in primary immunodeficiencies and we are collaborating with clinical immunologists to study the mechanisms contributing to disease pathogenesis in PIDs and autoinflammatory conditions.
