TopoTune is going to ICML 2025!🎉🇨🇦 Curious to try topological deep learning with your custom GNN or your specific dataset? We built this for you! Find out how to get started at geometric-intelligence.github.io/topotune/

Can geometry help explain how neuronal signals create consciousness?🤔🌐 Loved diving into this massive question with the brilliant @claire_i_webb thanks to @longnow & @berggruenInst ! Watch our full conversation here ⬇️ @ucsbece @geometric_intel @ai_ucsb

@louisacornelis @LouisVLang @ninamiolane @gbg1441 @geometric_intel @johmathe A super example of why critically evaluating GNNs is so important!! Well done🙌

⁠We're releasing OgBench: the first benchmark for GNNs on omics data in the n≪p regime. Every major benchmark (OGB, TUDataset, LRGB, GraphBench) operates where the number of graphs (n) far exceeds nodes per graph (p). But biology is the opposite: few patients, massive graphs.

🏥Congratulations to ECE Prof. Ramtin Pedarsani's team on receiving a UC Noyce Initiative award to develop robust vision-language models for clinical applications — part of a $3.4M UC-wide research push for computational health and cybersecurity.🤖 🔗tinyurl.com/mm9jb8x

🔬How do you study thousands of neurons at once? You build better tools. ECE Prof. Spencer Smith's SLAB Lab designed a scan angle multiplier that achieves the laser scanning trifecta: high speed, high resolution, and a larger area.🧠⚡ 📜tinyurl.com/36j7pa3d

@TAGinDS @ARLQ_AI @newtheoryai @UCSB @EPFL_en Also a huge shoutout to the incredible team of organizers behind this! @gbg1441 , @lev_telyatnikov , @louisacornelis @LouisVLang Marco Montagna, Olga Fink , @ninamiolane

We can’t wait to see your submissions! Full challenge guidelines and requirements are available here: geometric-intelligence.github.io/topobench/tdl-… Results announced at @TAGinDS Boston, Aug. 18–20. Participation does not require attending! #TDLChallenge #TopologicalDeepLearning #AI #ML #TAGinDS

🎉 Congratulations to ECE Professor James Buckwalter on being inducted as a Senior Member of the National Academy of Inventors!🏆 @AcadofInventors @ucsantabarbara @UCSBengineering 🔗tinyurl.com/ubk93ahf

Neural networks might speak English, but they think in shapes. Understanding their rich *neural geometry* is key to understanding how they work – and to debugging and controlling them with precision. Starting today, we’re releasing a series of posts on this research agenda. 🧵

@UCSBengineering is launching METL — the Master of Engineering & Technology Leadership — the first fully online master's degree at @ucsantabarbara, built for working tech professionals around the world.

Excited to share that our paper “Sequential Group Composition: A Window into the Mechanics of Deep Learning” was accepted to ICML 2026 in Seoul! Co-led with @giovannimarchet and @AdeleMyersPhD @hopfbifurcator @ninamiolane Paper: arxiv.org/abs/2602.03655

Thank you to everyone who attended our Long Now Talk at The Interval with mathematician and machine learning researcher @ninamiolane and science historian @claire_i_webb. They explored the question of consciousness from an unexpected direction: geometry. Geometry is the most ancient branch of physics, Miolane said. It’s the language we use to describe the curvature of spacetime and the general relativity of the universe. Might it also map the universe inside us? Stay tuned, the full Talk will be released on YouTube next week. Huge thanks to our partners @berggruenInst @NoemaMag for a magical evening. Photos by Anthony Thornton.

Such important work as AI becomes prevalent in healthcare! Go check it out in Rio🇧🇷

Interested in evaluating model explainability fairly? Come see me tomorrow at #ICLR2026 ! 📍 P4-#4017 (Pavilion 4) 🗓️ Thu 23 Apr, 10:30am-1:00pm Or just reach out to say hi!

Big news from our department! 🚀 Prof. Daniel Blumenthal and his group, in collaboration with @UMassAmherst, have demonstrated a chip-scale stabilized laser for trapped-ion quantum systems. 🔗bit.ly/4vgq7Wt @UCSBengineering @ucsantabarbara

Our Electrical & Computer Engineering program climbed to #13 among public universities and #25 overall in the 2026 @usnews graduate rankings – up two spots! 📈😼 Read more here: bit.ly/4smRU4N 🔗 @UCSBengineering @ucsantabarbara
