RESEARCH FOCUS
The area of interest in Dr. Shi’s lab is host-pathogen interactions, with special interest in the cellular immune responses to Cryptococcus neoformans and Trypanosoma brucei, as well as their transmigration into the brain across the blood-brain barrier. Both pathogens can survive in the bloodstream and invade the brain, causing brain infections. His lab has developed a mouse model system based on intravital microscopy to study intravascular interactions of host cells with the pathogens in living hosts. In addition, his lab studies the mechanisms involved in the clearance of C. neoformans by immune cells in the infected lung and brain. The long-term goal of his lab is to understand how the pathogens evade immune responses and cause infections.
