Gary Nabel

Gary J. Nabel is an American virologist and immunologist. He was the founding director of the Vaccine Research Center (VRC) at the National Institute of Allergy and Infectious Diseases (NIAID) from 1999 to 2012 and later served as chief scientific officer at Sanofi. He is the president and chief executive officer of ModeX Therapeutics, a biotechnology company based in Natick, Massachusetts. He has served as a director of SIGA Technologies since June 2021.

Education Nabel received a bachelor’s degree from Harvard University in 1975 and an MD–PhD from Harvard in 1982. He completed his residency in internal medicine at Brigham and Women’s Hospital in 1985, and then undertook postdoctoral research, which focused on the transcriptional regulation of HIV gene expression by the transcription factor NF-κB.

Scientific career and research From 1987 to 1999, Nabel led a research laboratory at the University of Michigan, with the support of Howard Hughes Medical Institute. During this time, he conducted research on gene therapy and transcriptional regulation of cellular and viral gene expression.

In 1999, Nabel was appointed as the founding director of the Vaccine Research Center (VRC) at the National Institute of Allergy and Infectious Diseases under the NIH. Research during Nabel's tenure at the VRC included studies on immune mechanisms of protection against Ebola and the identification of broadly neutralizing antibodies to the CD4 binding site on HIV.

In 2012, Nabel became the Chief Scientific Officer at Sanofi. He continued his research on neutralizing antibodies against HIV and led studies on antibody-mediated stimulation of CD8 T cells using multi-specific antibodies. In 2020, Nabel co-founded ModeX Therapeutics, a biopharmaceutical company primarily focused on these multi-specific antibodies. ModeX was acquired by OPKO Health in 2022.

Nabel has held positions across various scientific advisory boards and councils, including as Chairman of the Strategic Development and Scientific Advisory Council (SDSAC).
