Leor Weinberger’s lab studies fundamental processes of viral biology to develop innovative first-in-class therapies against HIV. The lab discovered a viral program that allows HIV to grow in some cells and remain dormant in others, and a new class of molecules that manipulate this program in infected individuals. The group developed and pioneered the concept of Therapeutic Interfering Particles (TIPs), single-administration, resistance-proof therapeutics that could treat HIV in resource-limited settings, such as sub-Saharan Africa and in injection drug users. The group also develops novel therapies for SAR-CoV-2, herpes simplex, and cytomegalovirus, the leading cause of birth defects and transplant failures.
Areas of Expertise
Weinberger and his team are known for discovering HIV’s latency “circuit”. HIV latency is a viral dormant state and the chief barrier to an HIV cure. Weinberger’s lab characterized the molecular mechanisms regulating HIV stochastic fluctuations (“noise”) and overturned dogma to show that HIV evolved circuitry to control latency by manipulating noise. These studies led to the lab’s discovery of a new class of molecules (noise enhancers), and of gene circuits in herpesviruses that are being exploited as a new class of antiviral targets.
The lab couples computational and experimental approaches, including quantitative, single-cell and single-molecule microscopy and mathematical modeling. An exciting illustration is the team’s recent effort to engineer resistance-proof, single-administration therapies for HIV. These therapies would benefit the highest-risk populations who most need therapy, and are aimed specifically at resource-poor settings, such as sub-Saharan Africa or at people who inject drugs.

Leor S. Weinberger, PhD, is the director of the Center for Cell Circuitry and a senior investigator at Gladstone Institutes. He is also the William and Ute Bowes Distinguished Professor, as well as a professor of chemistry, biochemistry, and biophysics, at UC San Francisco.
Weinberger earned a BS in biology and physics from the University of Maryland, College Park, and a PhD in biophysics from UC Berkeley, where he was a Howard Hughes Medical Institute Predoctoral Fellow. He received postdoctoral training at Princeton University as a Lewis Thomas Fellow, working with Thomas Shenk and David Botstein. Before joining Gladstone, Weinberger was an assistant professor of chemistry and biochemistry at UC San Diego.
Weinberger has been named an Alfred P. Sloan Foundation Research Fellow and won several awards, including the W.M. Keck Foundation Research Excellence Award, the California HIV/AIDS Young Investigator Innovative Development Award, and the Bill and Melinda Gates Grand Challenges Award. He is also the only individual ever to win the NIH Director’s Pioneer, Avant-Garde, and New Innovator awards. Weinberger is a member of numerous scientific societies and serves on the Innovation Review Panel for the Bill and Melinda Gates Foundation.
