Research Summary

Byrareddy Research CartoonDespite three decades since the discovery of Human Immunodeficiency Virus (HIV) as the etiologic pathogen of the origin of Acquired Immune Deficiency Syndrome (AIDS), the prospect of a protective vaccine against the virus remains a formidable challenge. Currently, ~35.5 million people are infected with HIV-1 worldwide [www.UNAIDS.org] and more than 50,000 new infections occur every year. Therefore, an effective AIDS vaccine remains an urgent need to prevent and control the spread of HIV. The research in my laboratory is focused on the development of an effective AIDS vaccine in a nonhuman primate model of human HIV infection using molecular biology, virology, immunology, systems biology, proteomic and genomic tools to understand host-virus dynamics and prevention strategies of HIV/AIDS and other infectious diseases in general.

My future and current research interests area outlined in the accompanying cartoon.
