Currently looking for Master Students who are interested in examining the impacts of pathogen on the epigenomes of human cells, using transcriptomic and epigenomic approaches (Feb 2018)

Research Interests: My main research focus has been to understand the molecular mechanisms facilitating the interaction of gene-regulation and environment (e.g., health, inflammation, infection) in disease susceptibility, vaccination and treatment. My research group has two main goals: (1) To define the regulation of innate immunity (interferon pathways) by genetic and environmental (epigenetic) factors, and examine their roles in susceptibility to infection. This study aims at identifying mechanisms of protection against HIV-infection and potential innate adjuvants for optimized vaccination. (2) To define the molecular impacts of HIV-infection on the regulation of host innate immunity and the gene expression of infected cell. This study aims at identifying markers for latent HIV-infected cells, and the altered expression and function of innate immunologic factors in HIV-infected patients.
