We study the multiple functions of catenins in cell-cell adhesion, cytoskeleton/nuclear signaling and lung repair after injury.

The array of organs in the animal body differ dramatically in their architecture, but cell-cell adhesion mediated by cadherins is a common principle. Our lab usually focuses on epithelia but cadherins are also active in migrating mesenchymal cells like these migrating testis myoblasts 1/n 🧪

Holy COW. Text analysis of comments on the OMB rule: overwhelming opposition, overwhelmingly not form letters. (But 9 in 10 comments supporting the rule ARE form responses, LOL) Whatever happens next, folks have stepped up.

At Heathrow hopefully heading home. Great @biologists.bsky.social Board meeting. Fun to be a small part of the team that makes @jcellsci.bsky.social , @jexpbiol.bsky.social , @dev-journal.bsky.social, @dmmjournal.bsky.social & @biologyopen.bsky.social happen. Choose society &non-profit journals!

1. A bit of evolutionary biology. I'm really intrigued by a new perspective piece from Steve Frank that explores connections between how natural selection creates systems that generalize and recent work in machine learning about the surprising capabilities of massively overparameterized systems.

Abstract. Natural selection encodes learned information in the genome. Learned solutions may be tuned specifically to past challenges, failing in altered e

💡 The laser was a solution that preceded every problem it would solve. Nobody in 1953 could list its applications, because those applications did not yet exist. That is what foundational research looks like before anyone knows what it is for.
The array of organs in the animal body differ dramatically in their architecture, but cell-cell adhesion mediated by cadherins is a common principle. Our lab usually focuses on epithelia but cadherins are also active in migrating mesenchymal cells like these migrating testis myoblasts 1/n 🧪
I did a bit of data analysis to inform considerations of this proposal. This is not completely simple since the number of grants a PI holds varies over time as grants start and end, and because this includes MPIs (multiple PIs) in addition to Contact PIs. 1/7

1/10 For decades, cellular aggregation was considered an evolutionary dead end. Cells could come together temporarily. But complex multicellular organisms like animals? Our study, led by JP Gerdt, with Ruibao & @jennahed.bsky.social suggests it may be time to rethink that🧵 #ProtistsOnSKy
To summarize: Most important Max Perutz was NOT an example of someone with a great idea who went against the establishment wisdom to solve an important problem that he had uniquely identified. He was part of an organized team working on this problem. He got lots of help. 11/14
I’m begging my fellow study section members to please “rescue” grants for discussion while this policy continues. We are going to lose lots of good grants to one unfairly negative reviewer otherwise. grants.nih.gov/grants/guide...

I essentially took the entirety of the first 2.5 years of my PhD, 55 hours/week and set them on fire. Nothing productive or useful arose. Those years are also the years that made me a very good scientist. Grunt work and failure and friction IS the work. There is no way around learning.
This is so, so well-articulated.

🧵 1/5 A new BioRxiv preprint reveals that membrane tension acts as a mechanical gate for lung cell fate during development! 🫁 Our Flipper-TR probe was key to assess live Cell Membrane Tension (CMT) Here’s how Flipper-TR unlocked a hidden layer of lung development & fibrosis. 👇 #Mechanobiology
5/5 The Takeaway: Flipper-TR didn't just report CMT; it identified CMT as a master switch linking physics to genetics. From development to disease, this probe proved that how "tight" a cell is matters just as much as its DNA. Read the full study: www.biorxiv.org/content/10.6...

Yay! 🎉 Another new lab coming online in 2026! HIGHLY RECOMMEND training with @jfhorner.bsky.social as he advances #proteoform level understanding of #mechanosensitive #adhesion proteins. Be sure to follow him and his upcoming work!
I am thrilled to share that I will be joining @tamuchemistry.bsky.social as a tenure-track Assistant Professor this summer. My research group will advance top-down mass spectrometry and proteomics to study the proteoform biology of cell–cell adhesion and phosphorylation in disease.
I conclude that NIH should make use of the large amounts of data that they have available to examine hypotheses before proposing developing new policies. 6/6
