Research Summary

My studies have been mainly focused on determining: 1) the cellular and molecular bases of host immune responses to infection and cancer, 2) ways of enhancing vaccination effectiveness through various ways, such as adjuvant strategies, immunization routes, DNA vaccines, subunit vaccines, peptide vaccines, delivery systems, dendritic cell application, and adenovirus gene delivery, 3) the underlying mechanism(s) of these applications for protective and therapeutic immunity. My current research interests are 1) to develop therapeutic vaccines against cancers of cervix, breast, colon and skin origins, 2) to study the immune escape mechansims of cancer cells and 3) to develop therapeutic antibodies against phlebovirus causing SFTS (severe fever with thrombocytopenia syndrome) and Ebola virus causing hemorrhagic fever.
