The research of George Y. Liu, MD PhD, focuses on understanding how interactions between Gram-positive pathogens and the host leads to a productive infection. From the bacterial side, Dr. Liu strives to identify novel immune evasion mechanisms that facilitate S. aureus or GBS invasion of the host. Conversely, he is also studying host antimicrobial mechanisms that keep bacterial infection in check. Ultimately, based on knowledge of host and bacterial defense mechanisms, he seeks to identify novel strategies to treat infections caused by antibiotic-resistant pathogens.
