Biography/Description of Research:

Vijayakumar Velu, PhD, completed his undergraduate and graduate program at the University of Madras, India. He completed his PhD in the year 2005, under the guidance of Dr. S.P. Thyagarajan, where he focused on viral hepatitis; particularly on HIV/HBV/HCV co-infection and demonstrated a higher prevalence of viral hepatitis co-infections in HIV infected individuals. He developed Hepatitis B vaccination strategies to improve HBV-immunity in HIV and HCV co-infected patients by conducting various clinical trials on newly developed Hepatitis B vaccine from India. He completed his postdoctoral training with Dr. Rama Rao Amara at Emory Vaccine Center. During his postdoctoral training he conducted studies to develop therapeutic strategies to enhance immune response during chronic SIV/HIV infection. In collaboration with Dr. Rama Amara and Dr. Rafi Ahmed, he demonstrated that blockade of a single inhibitory pathway (PD-1), results in enhancement of both cellular and humoral immune responses leading to decreased viral levels and enhanced survival of a pathogenic SIV infection. Velu’s research interest is to understand the basic biology of anti-viral T and B cell interactions for generating effective cellular and humoral immune response after vaccination and following HIV/SIV infection. He believes that a better understanding the roles of cellular mechanisms involved in generating effective immune responses, are needed to develop a new and better vaccines/therapeutics against HIV/AIDS. He collaborates with a number of researchers at Yerkes, including Drs. Rama Amara, Rafi Ahmed, Francois Villinger, Chris Ibegbu, Steve Bosinger.
