Research Interests

Dongzhu Ma's is interested in the study of the HIV/SIV diversity and pathogenesis. The AIDS pandemic is produced by two different viruses, HIV-1 and HIV-2 that emerged following cross-species transmissions of SIVs, the viruses that naturally infect nonhuman primate species (NHPs) in Africa. Our studies suggested that viral adaptation in the new host may play a decisive role for the emergence on new virus strains. Dongzhu Ma's current projects are focused on using nonhuman primate models to address issues of simian immunodeficiency virus diversity and pathogenesis in natural hosts and upon cross-species transmission. These studies may help us to control HIV infection in patients and AIDS pandemic.
