This was a really fantastic collaboration! Congratulations @mictott.bsky.social Rita Cervera Juanes, @svitlanabach.bsky.social and all co-authors! 🧪🧬💻🧠

Yes, I am on the academic job market looking to start my own lab at the intersection of molecular, computational, and systems neuroscience! If you think my work may be interest to your department, please don't hesitate to reach out. Thank you, Keri!

Congrats Michael! Really appreciate the brilliance & creativity you brought to the analyses and as always, sincere dedication to open science 🧪 🧠 @mictott.bsky.social is on the job market!! Amazing skillset spanning wet lab/computational at molecular, cellular + systems level - and across species!

Very excited to share my second postdoc, now out in Science Advances! We used targeted snRNA-seq to profile four major subnuclei of the primate across three species (including humans). 1/13 www.science.org/doi/10.1126/...

Congratulations to @mictott.bsky.social, Rita Cervera Juanes and @svitlanabach.bsky.social and all co-authors! Really fun collaboration w/labs of @vincentcostaphd.bsky.social and @stephaniehicks.bsky.social to better understand cell type and spatial heterogeneity across amygdala in primate 🧠!

Hot take #3: “BLA subdivisions contain specific subtypes of excitatory and inhibitory neurons. Hot take #4: Genes downregulated in PTSD load mainly onto specific subtypes of inhibitory interneurons that are highly conserved across primates.

Hot take #1: Amygdala neuron types are highly conserved across different primate species. No human specific innovations. Hot take #2: Canonical gene markers identified for murine amygdala neuron types are not especially informative inferring cell type identifies for the primate amygdala.

A spatially resolved transcriptomic atlas of the primate amygdala (human, macaque, and baboon) now out in Science Advances (www.science.org/doi/10.1126/...). The amygdala contains 32 types of neurons with many neuron types specific to particular subdivisions. Lots of updates from the preprint!

(1/10) We’re excited to share our new preprint (doi.org/10.1101/2025...), which uncovers the spatiomolecular landscape of the human nucleus accumbens (NAc), by integrating snRNA-seq with Visium spatial transcriptomics across 10 control donors. 🧠 #NAcLIBD #snRNAseq #10xVisium

Congratulations @kinnaryshah.bsky.social @mictott.bsky.social @svitlanabach.bsky.social & all co-authors! Wonderful collab btw @jhubiostat.bsky.social @jhu.edu and @lieberinstitute.bsky.social spatially profiling human dACC 🧠 #TeamScience 🧪 🧬 🖥️ Thank you #NIDA #NIMH for generous funding & support 👏

Check out this awesome new work led by @kinnaryshah.bsky.social uncovering the molecular landscape of the human dACC using both spatial and snRNA-seq! Kinnary used a wide range of analyses to characterize the dACC, as well as compare it to the dlPFC of the same donors.

I urge everyone to read Unbreaking’s new page on everything the govt is doing to destroy & diminish medical research funding. It’s the best thing I’ve read on this topic: @lizneeley.bsky.social & co have such done an incredible job. unbreaking.org/issues/medic...

#SpotSweeper is now published! Check our journal club session summary of the pre-print version by @lahuuki.bsky.social The new features @boyiguo.bsky.social + @mictott.bsky.social added in this revised manuscript enhance the use cases for #SpotSweeper: 👀 #VisiumHD data! youtu.be/f72XcXmtkfw?...

Congrats! 🎉 @boyiguo.bsky.social has a deep passion for both statistics and improving the treatment of psychiatric disorders. If any neuroscientists out there are looking for new collaborations in relation to 'omics projects - I would strongly recommend reaching out to him!

Great collaboration motivates methodological and biological innovation! Grateful for the opportunity to work together with @martinowk.bsky.social and @lieberinstitute.bsky.social, investigating the molecular pathology of neuropsychiatric disorder, coming soon! 😉

Excited to announce that I'll start as a tenure-track assistant professor @uofuphs.bsky.social this fall. #BiostatsElevated The #GUOmics lab will focus on developing biologically informed machine learning methods to decode spatial and population-scale omics data. Look forward to exciting colabs!
