Thrilled to start my lab at the @whiteheadinstitute.bsky.social @mit.edu and to join such a special community of creative and inspiring colleagues. The Sullivan Lab asks (1) how and (2) why infections make us sick, bridging immunology and neuroscience to understand host defense at the organism scale

Clearing some adult gut tissues. It is very, very gross and it smells terrible and I’m very excited about it

Being an American feels like getting on a school bus and then your bus driver decides to do a drive by

It's bittersweet to describe the success of #NIHPREP Scholars. You are awesome #scientists. Don't let anyone tell you otherwise. www.biorxiv.org/content/10.6...

Grateful for a new year filled with discovery, imagination, and community. No walls in sight

🎄✨ Getting into the holiday spirit? Why not add a little Pi to your plans! 🥧🏃‍♀️ Give yourself (or someone else!) a reason to stay active after the holidays by signing up for the 2026 Rise Up: Pi Race!

*First preprint from our lab* !!!!! How does the brain learn to anchor its internal sense of direction to the outside world? 🧭 led by Mark Plitt @markplitt.bsky.social & Dan Turner-Evans, w/ Vivek Jayaraman: “Octopamine instructs head direction plasticity” www.biorxiv.org/content/10.6... Thread ⬇️

"We find that while TAD boundaries pair more frequently than non-boundary regions, these interactions are infrequent and are uncorrelated with transcriptional activity of genes within the TAD. (...) These results suggest that TAD boundary architecture and gene activity are largely uncoupled"

Go @cobarnes27.bsky.social and team!!!!

"there's a new serif in town"

PDAC is a terrible malady and needs new inroads. We integrate a cell atlas, develop 3D tumoroid models, and map phenotypic spaces at scale. Very cool data inside! www.biorxiv.org/content/10.1..., www.biorxiv.org/content/10.1...

This paper is blowing my mind www.nature.com/articles/s42...

Is staying active, supporting your community, and having fun in your plans for 2026?? If so, mark your calendars for the 3rd annual Rise Up: Pi Race on March 14th, 2026!

Imagine, if you will, that NASA updated its website to suggest gravity might not exist, prompting CalTech and CERN to release statements saying, "With great sadness, we can no longer recommend listening to NASA." This is what's happening in epidemiology.

@hhmi.org Summer Undergraduate Research Experience - #CechFellows named in honor of Prof Tom Cech Deadline to apply: 12/22/2025 Spend 9 weeks in a paid, mentored biomedical research experience in an HHMI lab. See you next summer!!! www.hhmi.org/programs/cec...

What an honor to be recognized as one of @thetransmitter.bsky.social Rising Stars of Neuroscience 2025! Check out this year's award winners and their contributions to neuroscience at www.thetransmitter.org/early-career...

My brilliant 4 year old daughter did not realize it but she painted the myenteric plexus, submucosal plexus, and mucosal glia

And here is the story after peer review. This work highlights our current approach, which is to use Piezo channels to uncover new areas of biology that are shaped by mechanical forces: www.science.org/doi/10.1126/...

What if inflammation doesn’t just bring in immune cells, but changes the entire neighborhood? Our new preprint led by brilliant MD/PhD student @kateletai.bsky.social in collaboration with the Cominelli lab and @biancaislam.bsky.social explores this question: www.biorxiv.org/content/10.1...

People might not realize - this wasn’t just one problematic person. He was (and is) influential. And this has real consequences. “Female scientists who have kids can’t be taken seriously” and many other jabs at women have been directly said to me, within the last decade, by other scientists.

THIS WEEKEND! Register to hear from me and two of my lab members! We will talk about: -our journey in science -what we study in the lab -the importance of investing in science -how supporting international scholars and scientists from diverse backgrounds benefits everyone

One analytical model shows that, as of November 5th, the dismantling of U.S.A.I.D. has already caused the deaths of 600,000 people, two-thirds of them children. https://newyorkermag.visitlink.me/jUzNSc

The Leading Edge Fellows gathered this week to celebrate Zara Weinberg, a beloved member of our community. Our 7th cohort of Leading Edge Fellows (2026) will be named in her honor. The Zara Weinberg Leading Edge Cohort application is now open! Due Feb 2. www.leadingedgesymposium.org/apply/

IMAX scientific talk (39 feet by 10 feet). So much fun at #TGS2025!

The Allen Institute is a premier scientific powerhouse that upholds values - open science, team science, and collaboration - that promote the progress of science rather than individual advancement. Past NGLs are leaders in their fields. To be a part of this group is a huge honor!

Meet our 2025 cohort of Next Generation Leaders! For the next 3 years, they will network with other rising stars, participate in professional development, and share their ideas for future research directions.

I shouldn’t have to share this. I’m so sad and angry at what the American healthcare system forces people to go through My uncle is in critical condition and stuck in an out-of-network ICU. Please share, donate, and VOTE TOMORROW. It is one small way to push for something better gofund.me/9d9648949

👉 We generated a starter pack for #neurogastroenterology and enteric #neuroscience! Let's connect and bring gut-brain research and clinical neurogastroenterology to the next level! 🌐 go.bsky.app/3Z82PbH

Next weekend, members of our lab are hosting a Teach-In! Open to everyone, in person and virtual. Come learn about the brain inside your gut and what happens when misinformation and defunding threaten research

Lab’s 1st preprint! Menstruation is understudied due to societal taboos + a biological challenge: mice (a key system for research + drug discovery) don’t menstruate. @cagricevrim.bsky.social made menstruating mice + used them to discover early events in menstruation. He is on the job market!

Congratulations @karalmckinley.bsky.social & lab on their groundbreaking recent preprint establishing + characterizing a chemically inducible model of menstruation in mouse: www.biorxiv.org/content/10.1... My jaw dropped when I heard this presented earlier this year. Incredible.

Neuroscience faculty job Alert! We are hiring at Case Western Reserve University School of Medicine! Apply at apply.interfolio.com/171533. Please repost.

We’re hiring! My new Gut–Brain Axis Lab at Northwestern is looking for a Research Technologist 2 to help build the lab and explore how the nervous system shapes gut health and disease. 🔬 Apply here: myhr.northwestern.edu/psp/hrnu/EMP...

Meet the lab! Aaliyah Staples-West is a second year PhD student studying how the nervous system in the human gut develops. Aaliyah says that being in the PhD program at CWRU has sharpened her critical and analytical thinking.

Thrilled to share our paper that just came out in PNAS! We asked a deceptively simple question: What happens when S. aureus adapts to vancomycin, a critical first-line antibiotic? 1/5
