Research Summary

The Davis lab uses the zebrafish larva as a model host to understand how the innate immune system interacts with potential pathogens over time, and how that interaction determines outcomes like microbial clearance, persistence or disseminated disease. The basic biology of granuloma formation and function is a major focus. Specific infections under study include cryptococcosis and mycobacterial infection.
