The Gruber Foundation today recognized five scientists who have made significant contributions to the fields of cosmology, genetics, and neuroscience. Recipients of the Gruber International Prize Program will receive a total of $1.5 million for research that inspires and enables fundamental shifts in knowledge and culture.
Recipients of the 2026 awards are Alexei V. Filippenko, a professor at the University of California — Berkeley, Ken’ichi Nomoto, a professor at The University of Tokyo, and Stanford Woosley, a professor at the University of California — Santa Cruz, the recipients of the 2026 Gruber Cosmology Prize; Alan G Hinnebusch, a Distinguished Investigator at the National Institutes of Health, recipient of the 2026 Gruber Genetics Prize; and John L.R. Rubenstein, a professor at the University of California — San Francisco, recipient of the 2026 Gruber Neuroscience Prize.
Patricia Gruber and her late husband, Peter Gruber, established an International Prize Program in 2000 to honor and encourage outstanding individuals in the sciences and human rights. In a succession plan to perpetuate this legacy, The Gruber Foundation was established at Yale in 2011.
All three prizes will be presented later this year.

The 2026 Gruber Cosmology Prize
Alexei V. Filippenko (the University of California — Berkeley), Ken’ichi Nomoto (The University of Tokyo), and Stanford Woosley (the University of California — Santa Cruz) were selected for their decades-long studies of supernovae — exploding stars that have proven invaluable in understanding the composition and evolution of the Universe. The official citation honors them for “transforming supernovae from poorly understood stellar explosions into the basis for a quantitative, predictive, and empirically validated framework.” The three recipients have studied supernovae through complementary approaches, Filippenko as an observer and Nomoto and Woosley as theorists. Taken together, the citation says, Filippenko, Nomoto, and Woosley’s “trail-blazing work links stellar evolution, explosive nucleosynthesis, the origin of heavy elements, and the chemical evolution of the Universe, and supports the use of supernovae for precision cosmology.” They will evenly divide the $500,000 award, which they will receive on Nov. 10 at the “Illuminating the Cosmos” conference at the Max Planck Institute for Astronomy and House of Astronomy in Heidelberg, Germany.
The 2026 Gruber Genetics Prize
Alan G. Hinnebusch, a Distinguished Investigator at the National Institutes of Health, was selected for his pioneering work that established both the paradigm and the detailed mechanism of translational control that underlies the Integrated Stress Response, a pivotal mechanism whereby eukaryotic cells reprogram protein synthesis under stress. Hinnebusch’s work has led to a greater understanding of how cells respond to stressors such as amino acid starvation and viral infections. Dysregulation of the integrated stress response has been linked to neurodegeneration, metabolic disorders, and cancer. “His pioneering studies have led to an understanding of a universal translational control mechanism by which cells respond to stressors such as starvation, viral infections and heme deficiency,” said Philip Hieter, a professor at the Michael Smith Laboratories at the University of British Columbia and a member of the Selection Advisory Board. “These fundamental discoveries using yeast as a model organism have led to potential therapies that are being developed in the clinic.” The 2026 Gruber Genetics Prize, which includes a $500,000 award, will be presented to Hinnebusch in December in San Diego at Cell Bio 2026, the annual meeting of the American Society for Cell Biology.
The 2026 Gruber Neuroscience Prize
Dr. John L.R. Rubenstein, a professor at UCSF, was selected for his pioneering work on mammalian forebrain development, a structure which is responsible for functions such as cognition, memory and perception. This work has helped shed light on causes of multiple neurological and psychiatric disorders. These discoveries have led him and collaborators to develop a novel therapeutic approach in which cortical interneurons are transplanted into the hippocampus of patients with intractable focal epilepsy. Initial clinical trials have already yielded encouraging results. “Rubenstein’s work has led to an understanding of how the mammalian forebrain develops, which includes elucidating the transcription factors and regulatory sequences that are involved in forebrain patterning,” said Joshua Sanes, Jeff C. Tarr Professor of Molecular and Cellular Biology at Harvard and chair of the Selection Advisory Board to the Prize. “This work has also led to a greater understanding of developmental conditions such as epilepsy and autism spectrum disorder.” The Gruber Neuroscience Prize, which includes a $500,000 award, will be presented to Rubenstein on Nov. 15 at the Annual Meeting of the Society for Neuroscience in Washington, D.C.
