The main research interest is the understanding immune responses against viral infection, with a particular focus on T-cell responses against HIV, EBV, SAR-CoV-2 and other viruses. The main aim is to study the correlates of protective immunity that can be used in the vaccine development for preventing infection. We are currently investigating how these protective immune responses are only generated in the individuals with better clinical outcomes of infectious diseases but not in others who have poor clinical outcomes. This leads to the study of how to improve the virus-specific T-cell responses that are likely to be protective against viral infection. We also focus on molecular biology, virology, epidemiology and effects of viral infectious diseases.
