Our paper "Rarely categorical, highly separable representations along the cortical hierarchy" is now out in Nature! www.nature.com/articles/s41... In this paper, we studied whether the brain is well-organized and interpretable, both globally and locally. (See thread below.)

Our paper "Neural timescales from a computational perspective" is finally out in @natneuro.nature.com: www.nature.com/articles/s41... We discuss how computational models and methods can distill empirical observations on neural timescales into quantitative, testable theories of brain computation.

Most of the statistical tests you learned in stats class — t-test, ANOVA, correlation — are actually special cases of a single thing: linear regression. Ch 7 of Experimentology argues that thinking in models, not tests, is more flexible and a better foundation for theory. 🧵 experimentology.io

Week 3 of summer of papers! Here we go! 📣🎥📜 If a recurrent dynamical system is selected only for prediction, what structure does it evolve? Not just: can it predict complex timeseries (like Kuramoto-Sivashinsky)? But: what does prediction do to the machine? 1/n 🧵👇 arxiv.org/abs/2606.22765

Some incredibly exciting news that still feels a bit surreal: I am starting my research group @mpicybernetics.bsky.social! The best part? We are hiring at all levels! Curious about the science we plan to tackle, read along :) #NeuroSky

This one cracked me up!

this is such a powerful way to support the international neuroscience community, and a massively rewarding experience and great line on your CV to boot. please join us!

Neuromatch has been denied our Office of Foreign Assets Control "Iran license" renewal. We had renewed successfully before, but now our request is “inconsistent with current U.S. foreign policy.” I am absolutely gutted by this denial.

If you're interested in doing a 2 year Schmidt "AI in science" postdoc fellowship in neuroscience/AI stuff with me starting in July or Oct 2027 take a look at this and get in touch soon. We've had a lot of luck recently getting these fellowships. www.imperial.ac.uk/electrical-e...

Do you have a Republican rep? Probably worthwhile to spend the day yelling at them and telling all your neighbors to do the same

Dear US citizens, Please, do as much as you can to stop this madness. Don't let your president use a nuclear bomb on Iran. The world has suffered enough! Call your senators! Stop him! Please!

Last night, US/Israeli strikes bombed Sharif University, my alma mater, heavily damaging the IT Center, Philosophy of Science building, EE, and more. Trump spoke of sending Iran "back to the Stone Age." That is the goal of this war. Scientists worldwide should speak up against these atrocities.

I don't know about that, but I do know that defending a PhD would count on Resume! 😎👨‍🎓

Attention fluctuates over time and across contexts—how is this reflected in the brain?🧠 Fitting a dynamical systems model to fMRI data, we show that the geometry of neural dynamics along the attractor landscape reflects changes in attention.

7 days of digital black-out in Iran. One week of darkness... Approximately 20,000 innocent, empty-handed protesters got killed!

Over 12,000 people peacefully protesting against the current Iranian regime have been killed in just one week. These are among the darkest days of 2026. Shame on every country that recognizes the Iranian regime as a legitimate government that murders its own people.

I left Iran in Jan 9th. I was there to visit my family. Meanwhile protests and strikes began. I left the country with one of the few last flights before the digital blackout in Iran. I hugged my family and said goodbye in the airport and never heard from them since then. There is zero connection.
