HIV • COVID-19 • SARS-CoV • innate immunity • interferon • antivirals

Research Interests

My research aims to understand the host innate immune responses to viral infections. My team uses the findings to understand viral pathogenesis and transmission and to guide the development of effective antiviral therapeutics. Specifically, we investigate how host cells produce antiviral interferons in response to infections by HIV or SARS-CoV-2, and how these two highly pathogenic viruses overcome and evade this first line of host defense. We are dedicated to the discovery of new HIV treatments and the compounds that can effectively inhibit SARS-CoV-2 and thus cure COVID-19. My lab has also pioneered the application of the CRISPR gene editing tool in curing HIV infection.
