6th-yr neuro PhD candidate working towards precision fMRI in the subcortex w/ Dr. Stephanie Noble in the NeuroPRISM lab at Northeastern Univeristy 🧠

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)

OHBM trainees, let's get creative! 🎨 Together with Brain Art SIG we are launching the Sticker Design Competition. Design a sticker featuring the SP-SIG logo! 🏆 Winning design will be distributed at the OHBM 2026 meeting in Bordeaux. 📅 Deadline: May 1, 2026 👉Details and submission: bit.ly/4caXG3m

I’m excited to share that I was elected to serve as the inaugural Virtual Events Coordinator for the Organization for Human Brain Mapping Student & Postdoc Special Interest Group! A huge thank you to the open-science community for trusting me to help shape this new and exciting position! 🧠 #OHBM

For our inaugural Precision Brain & Mental Health Hack, we had over ✨ NINETY FIVE ✨ researchers, scientists, students & faculty register!!! Feeling very proud and grateful for this amazing team and event!!

The NeuroPRISM Lab 🧠 is in the news! The article touches on the Effect Size Explorer, the Power Calculator, and my own Local CSF Correction Pipeline — a scalable preprocessing pipeline for correcting local physiological noise in the subcortex. news.northeastern.edu/2025/09/02/n...

Precise maps of the brain’s deepest corners are made possible through tools developed by these Northeastern researchers

Northeastern researchers have developed a set of tools that offer precise mapping of the brain’s deepest corners.

These past two years have had no shortage of challenges as a new PI, but this team has been a constant inspiration. Glad to recognize their commitment to advancing rigor in research. @halleeshearer.bsky.social @alexkfischbach.bsky.social Fatemeh Doshvargar @strfabs.bsky.social Catherine Cahill

Excited to share that the NeuroPRISM Lab has been awarded the #NINDS Early-Career Rigor Champions Prize! A major accomplishment for the lab, but especially reflects the leadership of our PI, Dr. Stephanie Noble! 🧠 @sneuroble.bsky.social 🧠 @halleeshearer.bsky.social 💻 @strfabs.bsky.social

Excited to share our tool for exploring fMRI effect sizes at OHBM on Friday at 11:30 in the Neuroinformatics and Data Sharing session! If you can’t catch the talk, I’ll also be at my poster on Friday and Saturday (#1822)

@alexkfischbach.bsky.social & @halleeshearer.bsky.social in action 🙌🏽 And congrats to all the poster presenters today—great to see so all the neuroimaging methods represented at #CNS2025

Amidst continued chaos, the lab will be at #CNS2025! Please come say hi, and we can all talk about promoting progress in brain research Sat 10:30 AM (blitz), Mon 8 BrainEffeX @halleeshearer.bsky.social Mon 8 AM: Subctx artifact @alexkfischbach.bsky.social Tues 8 AM: NeuroPowerX @strfabs.bsky.social

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) 🧠

Curious if movie-watching can improve the reliability of FC from a certain brain region? Check out our Shiny App vanderlab.shinyapps.io/movie_stuff/ to interactively explore the results from our ROI-based comparison of the test-retest reliability of FC between movie-watching and resting-state fMRI.
