This department primarily focuses on the fundamental insights of the pathogenic genetic factors of the host and the pathogens of tropical infectious diseases such as Dengue fever, malaria and Chagas disease, through the application of immunology and genetics. With the understanding of the dynamic host-pathogen interactions, we are further concerned with the development of new tools to fight against these diseases including novel therapeutics (drugs) or vaccines.
