I specialize in immunology, virology, and emerging infectious viral diseases. My research focuses on understanding pathogen-host interactions to enhance our knowledge of immunity and develop practical strategies for detection, control, treatment, and vaccine development.

     I work mainly with RNA viruses with special interest in influenza A virus. Apart from conducting basic research to enhance our understanding of virus pathogenesis, my current focus revolves around investigating broadly reactive immunity against influenza through the study of influenza virus hemagglutinin stalk-specific antibody responses.

     I am also interested in the receptor binding specificity of influenza A virus and how different hemagglutinins bind to sialic acid-containing receptors, and their implications for pathogenicity and transmissibility across host species. Furthermore, my research interest extends to the development of vaccine candidates against infectious viral diseases, utilizing molecular, cellular and virological techniques to select and develop candidate vaccine strains.
