So glad to finally share work years in the making! What started with fMRI effect size benchmarks ended up showing that conventional study planning detects ~half of expected brain effects, suggesting more distributed processes than the lit shows (+ new methods for mass univ effect/power estimation)

Useful piece on AI in academic training: “The instinct[…]comes from years of failing at exactly the kind of work that people keep calling grunt work. Making the models smarter doesn't solve the problem. It makes the problem harder to see.” h/t @laurelgd.bsky.social ergosphere.blog/posts/the-ma...

The machines are fine. I'm worried about us.
On AI agents, grunt work, and the part of science that isn't replaceable.

These are the most challenging times for early-career scientists and engineers. My team is doing its bit to help by maintaining and even expanding our database of funding opportunities for early-career researchers. We found 437 of them. Download it freely here: research.jhu.edu/rdt/funding-...

Spatial heterogeneity of CSF related-noise in fMRI: why it matters and what we can do about it. My work at #OHBM2025 provides evidence for taking a region-specific approach when isolating CSF artifact in the subcortex. Swing by #P1358 on Fri/Sat to discuss!

Had a great time presenting my work at #CNS2025. A huge thank you to my advisor @sneuroble.bsky.social for helping me bring this project to life. Incredibly excited to see how well received our poster was and I can't wait to share new developments at OHBM this June! #fMRI #CSF

Improving fMRI signal quality starts with better noise modeling. My project at #CNS2025 shows how localized region-specific CSF correction may better isolate neural activity and increase sensitivity in the subcortex. Come by my poster #D138 to learn more! (Mon. 8:00-10:00AM) 🧠
