Simulations are no longer just “nice to have.” They’re reshaping how we do statistics. Care to learn more? Check out our paper arxiv.org/abs/2503.24011, accepted for publication in the upcoming theme issue of Philosophical Transactions A.

Awesome new preprint from @jasonleng.bsky.social! Deadlines in decision making often truncate too-slow responses. Failing to account for these omissions can (severely) bias your DDM parameter estimates. They offer a great solution to correct for this issue. doi.org/10.31234/osf...

Two flagship papers from the International Brain Laboratory, now out in ‪@Nature.com‬: 🧠 Brain-wide map of neural activity during complex behaviour: doi.org/10.1038/s41586-025-09235-0 🧠 Brain-wide representations of prior information in mouse decision-making: doi.org/10.1038/s41586-025-09226-1 +

So excited to share our new preprint! We used behavior & pupillometry to examine how reinterpreting negative emotions shapes memory for emotionally charged events. Huge thanks to my spectacular advisor, Dave, for all his help and support with my first project of grad school! Check it out 👇

When I first started working with resting state fMRI as a postdoc, there was a lot of skepticism about what we could learn from it. 20 years later, it's hard to imagine where the field of neuroscience would be without it. Here's a summary 🧠 www.nature.com/articles/s41...

How to make #autodiff user-friendly? What lies beyond the safety of Python-world? Why does it matter for scientific machine learning? All this, and more, in our latest preprint with @adrhill.bsky.social! Spoiler alert: it describes the most useful software I ever wrote. arxiv.org/abs/2505.05542
