That was unexpected! Huge thanks to Neuroimaging PIA for this award, and congrats to the other winners! If you want to chat about WMH pathophysiology and a potential signature of non-vascular neurodegeneration-related WMHs, come by my poster Tuesday-442 #AAIC2024

When you abuse for-loops in UK Biobank and generate a comically large graph that needs to be 8 feet wide to be readable, you gotta print it! Now the whole lab can look at the white matter hyperintensity patterns of 646 different diagnoses in UK Biobank!!

Here’s some new work from the group from Tyler Agyekum This papers got some hippocampus, some microstructure, some ageing, and some great multivariate analysis!! 👇🏾👇🏾 biorxiv.org/content/10.110…

5 years ago, on the heels of 28andMe, our team designed a new precision imaging experiment: scanning an individual’s brain throughout her entire pregnancy. We are excited to share that these findings are out today in Nature Neuroscience! nature.com/articles/s4159…

Just putting it out there again we're hiring for 1) Scientific programmer 2) Immunohistochemistry technician RT's appreciated! Feel free to DM or email me if you have questions!

TLDR: When age-matching pre- and post-menopausal women in UK Biobank, we don't find an effect of elevated WMHs after menopause! Hopefully this brings nuance to the field and motivates the acquisition of data purposefully designed to investigate women's health in aging

Delighted to see this work, led by Matt Danyluik, out in Imaging Neuroscience Excellent technical piece on the caveats of methods for performing inference using PLS. A great piece of work for those using the technique and those who are interested in its robustness and reliability

It’s out! 🎉 Check our paper “Disentangling the effect of sex from brain size on brain organization and cognitive functioning” 🧠, where we explored sex differences in the brain while removing the effect of brain size differences. 1/10

New paper led by Aurélie Bussy now out in Neurobiology of ageing. We use non-negative matrix decomposition using morphological and qMRI measures (T1, T2*) to understand the relationship between GM and microstructure in the Alzheimer's spectrum. sciencedirect.com/science/articl…

If you’re into rodent fMRI, you should definitely check this work led by Mila Urosevic! A great resource for anyone developing an acquisition protocol and who wants to improve measurements of resting-state networks.

After 3 years of "just one more analysis", happy to share our preprint! Building on previous post-mortem findings of non-vascular WMHs, we identified a specific signature of neurodegenerative WMHs in vivo using microstructural MRI and normative modeling doi.org/10.1101/2025.0…
