My laboratory conducts research on host-pathogen interactions of the zoonotic apicomplexan parasite, Cryptosporidium. Our work encompasses both basic and translational research on mucosal innate immune responses and molecular mechanisms of host cell invasion. We also have an ongoing drug discovery project that involves screening compounds produced by symbiotic bacteria of marine mollusks for anti-parasitic activity.
