Dr. Robert Gallo: Insights from a Lifetime in Science

Virology vanguard Dr. Bob Gallo is far from ready to slow down. Now in his seventh decade as one of America's top scientists, he could easily sit back and enjoy the fruits of his numerous and pioneering achievements. His groundbreaking work began in the 1970s with research into human retroviruses, including the discovery of the T-cell growth factor (IL-2) and the identification of the Human T-Cell Lymphotropic Virus (HTLV-1) in 1980, earning him his first Lasker Award, often referred to as “America’s Nobel Prize.” His subsequent research led to the identification of HIV-1 as the cause of AIDS, securing him a second Lasker Award. In the 1980s, he was the world’s most cited scientist. Along with his team, he developed the first HIV blood test, crucial for understanding the spread of AIDS and managing HIV patients. In the mid 1990's Gallo and his collaborators discovered chemokines, naturally occurring compounds that were essential for understanding how HIV infects cells. Dr. Gallo later founded the Institute of Human Virology at the University of Maryland School of Medicine in 1996 and co-founded the Global Virus Network (GVN) in 2011 to enhance global virus detection and management. Recently, Dr. Gallo and his team moved to Tampa, the new global headquarters for GVN, where he now serves as director of the University of South Florida (USF) Virology Institute and Head of the Microbial Oncogenesis Program at the Cancer Institute at Tampa General Hospital (TGH).

In the first part of this wide-ranging interview, Dr. Gallo shares insights into his entry into virology and his initial research into the etiology of certain cancers. This work included crucial discoveries around T cell growth factors, paving the way for identifying HTLV-1. He discusses his collaboration with CDC epidemiologists, which led to recognizing AIDS as being caused by a retrovirus. Once the HIV virus was identified as the cause, creating the first blood test for HIV had profound impacts on the epidemic and patient care.

In the second segment, Dr. Gallo discusses the origins of the HIV virus and its early global spread. He also reflects on the COVID-19 pandemic, why the focus on its origins is irrelevant and reflects on how to rebuild public trust in science and medicine, which may have been damaged during the pandemic.

In the concluding segment, Dr. Gallo talks about his reasons for joining USF Health and TGH and the research areas he finds most promising going forward. He speculates on the prospects for an HIV vaccine, the impact of artificial intelligence on virology, and why he doesn’t necessarily worry about the threat of the next global pandemic. Finally, Dr. Gallo opens up about how the early loss of his young sister deeply affected his life and his desired legacy.

Dr Vega would like to thank her friend Job Meiller, her YES Man, for the wonderful musical contributions and coming through on every idea she has. This time he contributes his renditions of Bruce Springsteen's "Streets of Philadelphia" and "Your Song," by Elton John. Thank you Job!
