Meet Harry B. Gray (@Caltech) #CitationLaureate 2026 in Chemistry. ▶️ Hear him reflect on a career spent exploring one of nature's most fundamental questions: how electrons move through living systems. #CitationLaureates
On October 8, the U.S. Department of Energy announced a second round of funding for its Genesis Mission. Among the projects that will receive funding is a Caltech effort that will use AI to help identify new and better catalysts, materials that speed up chemical reactions.
Kareem El-Badry, associate professor of astronomy at Caltech, has been selected as one of 20 Packard Fellows for 2026. Much of El-Badry’s work is focused on spotting hidden populations of black holes using data from large-scale sky surveys. caltech.edu/about/news/kar…
Really excited to share that our work on TorchLean at @Caltech, with @AnimaAnandkumar, has been selected for support through the 2026 AI for Math Fund, run by @RenPhilanthropy and funded by @xtxmarkets. Since releasing TorchLean, we’ve expanded from verified neural-network execution to autodiff, floating-point semantics, verification, and GPU execution; uncovered bugs and semantic mismatches across major ML stacks; and seen teams at major companies and U.S. national labs begin using it for ML verification. With this support, we’re excited to push toward formally verified GPU execution and GPU kernel verification—part of a broader goal of making AI and scientific computation trustworthy across the full stack. TorchLean: leandojo.org/torchlean.html Congrats to all the winners!
We're delighted to announce the winners of this year’s grants from the AI for Math Fund, powered by founding donor @xtxmarkets: 22 winners, 30+ organizations, selected from 400+ applications across 50 countries. Backed by a record $17.1M from XTX Markets, bringing their total

Alireza Marandi, professor of electrical engineering and applied physics, has been named a 2026 Moore Experimental Physics Investigator. He is one of 21 new investigators named this year by the Gordon and Betty Moore Foundation. caltech.edu/about/news/ali…
@francesarnold @Princeton Well deserved, congratulations again!
In recent weeks, a surprisingly contentious debate has been making headlines around the world: What role should artificial intelligence (AI) play in mathematics? caltech.edu/about/news/cal…
Congrats to @Oratomic on this milestone. We're proud to see work rooted at Caltech helping advance the future of quantum computing through the contributions of faculty, alumni, students, and researchers including @DolevBluvstein , @RobertHuangHY, Manuel Endres, and @preskill.
It's an exciting time @TeamOratomic. We are on a focused mission to build a utility-scale, fault-tolerant quantum computer, and have now raised $775M since our launch in March 2026. Find out more about us here: oratomic.com/news/mission
Congratulations Frances! 🧡
The University will present its top awards for @princetonalumni to @francesarnold '79, 2018 Nobel laureate and engineering professor at @Caltech, and Mary Brunkow *91, 2025 Nobel laureate and distinguished investigator at the @isbsci in Seattle. Arnold, who graduated from
Caltech faculty members Mitchell Guttman and Markus Meister (PhD '87) have been selected to receive "high-risk, high-reward" grants from the National Institutes of Health (NIH) for cutting-edge work in biomedical science and neuroscience. caltech.edu/about/news/cal…
@GeorgieC @rootsofprogress @NASA @NASAJPL And what a great representation you always are! 🧡
