Our Teams

Dr. Chun is our collaborator on UB-421 clinical development. He is currently the Chief of the HIV Immunovirology Unit at the National Institute of Allergy and Infectious Diseases (NIAID), of National Institutes of Health (NIH).

Dr. Chun received his Ph.D. from the biochemistry, cellular, and molecular biology graduate program from Johns Hopkins University School of Medicine where he discovered and characterized latently infected, resting CD4+ T cells in HIV-infected individuals. Dr. Chun began his postdoctoral research work in the Laboratory of ImmunoRegulation (LIR) under Dr. Anthony Fauci at NIAID in 1997. He was the first to demonstrate that the latent HIV reservoir persists in virtually all infected individuals receiving antiretroviral therapy despite effective suppression of plasma viremia. In addition, he demonstrated that early initiation of antiretroviral therapy leads to a decay of the latent viral reservoir and introduced the concept of “virus purging” in HIV-infected individuals.

Dr. Chun was appointed to the position of staff scientist in 2001, and was selected as one of the Earl Stadtman Investigators, and appointed a tenure track investigator position in the LIR in June 2016. Dr. Chun is the author/coauthor of numerous peer-reviewed publications in high impact journals such as New England Journal of Medicine and Nature Medicine, and participated in several pioneering clinical trials in HIV treatment.
