Research Interests
My research interests focus on development of vaccines, and studies on the immunology of ferrets and host-pathogen interactions in response to respiratory viral infection, especially with influenza virus. Due to their emulation of clinical features associated with human disease and similar physiological/anatomical features, we utilize ferrets as our pre-clinical experimental animal model to evaluate vaccine efficacy. The serological protection, virus replication in the upper and lower respiratory tracts, as well as innate and adaptive immunity in different tissues are measured following immunization or virus infection. Meanwhile, we are developing immunological reagents and in vitro assays for in-depth dissection of humoral and cellular immune responses. We aim at identifying immune correlates of broader protective immunity induced by innovative universal influenza virus vaccines or virus infection in the ferret model.
