Area of interest

My lab studies how the how programmed cell death can be used to defend against intracellular infections. Programmed cell death can be initiated by the infected cell itself, or by cytotoxic lymphocytes both in the innate and adaptive immune system. Our interests began with the study of how cytosolic inflammasome sensors detect bacterial pathogens. For example, we showed that NLRC4-caspase-1 detects the activity of the bacterial type III secretion system, whereas caspase-11 detects the LPS shed from Gram-negative bacteria that invade the cytosol. In response, caspase-1 and -11 drive pyroptotic programmed cell death, where the infected cell literally explodes. More recent work has led us to study how natural killer cells and cytotoxic T cells drive programmed cell death to defend against intracellular pathogens. We also have interests in expanding into how other forms of programmed cell death defend against infection, but also may become immunopathologic during inflammatory disease.

We study a variety of pathogens that target the gastrointestinal tract, including intestinal pathogens as well as pathogens that are tropic for infection of the liver. We study host adapted pathogens such as Salmonella Typhimurium and Listeria monocytogenes. We also study environmental opportunists that the immune system normally eradicates without a trace, but which can be deadly when immune defenses are absent, such as Burkholderia thailandensis and Chromobacterium violaceum.
