How do non-coding variants in enhancers cause human disease? Here, in my main PhD work with @evgenykvon, we uncover a surprising mechanism, with generalizable implications for human genomics. tinyurl.com/89tdkevu n/

New paper from the lab: Our teeth arose as sensory organs on the outside of the body of ancient jawless fish.!! Congrats to Yara Haridy and the team! Open Access Paper: nature.com/articles/s4158… News and Views: nature.com/articles/d4158… Background and video: phys.org/news/2025-05-t…

A new @ScienceAdvances study has found that the coelacanth—an evolutionarily ancient fish often nicknamed a living fossil—lacks 11 jaw muscles that researchers previously thought it had. scim.ag/4iZXPIt

⚠️⚠️Happy to share our latest work! ⚠️⚠️ Team work made dream works...@DeliaCicciarel1 No spoiler, but if you want to know how PHF2 regulates lipid droplet turnover in MuSCs during muscle repair...👇👇👇 biorxiv.org/content/10.110…

Our work on the role of endogenous electric fields in guiding collective cell migration in vivo is finally out @NatureMaterials ! nature.com/articles/s4156… Congrats to all the authors, specially Fernando and @Sofia__Moreira from my lab #bioelectrics #devbio #cellmigration #xenopus

The outer ear is a mammalian innovation but where did it come from? In our study in @Nature, @MathiThiru95 and colleagues find that the outer ear arose from modification of an ancestral gill program first originating in marine invertebrates. nature.com/articles/s4158… 1/n

🚨Why can’t mammals regenerate legs or arms like frog tadpoles or salamanders? Our preprint tackles (part of) this BIG question with surprising findings about oxygen sensing 🔗biorxiv.org/content/10.110… Happy New Year, everyone! 🎉 🐭 vs 🐸 #evodevo #regenerative #cellbio 🧵👇

It’s crazy how talking with a science buddy is simultaneously what’s most likely to move the project forward and the thing that’s least prioritized in our schedule.

Happy Holidays to all! Here’s a little 🎄 gift for those who enjoy the anatomy of extant animals: a PDF of a really great atlas of avian anatomy (Ghetie 1976)—bit.ly/3rs3xrA. For the story behind this PDF, check this out: bit.ly/4gPt6Nr.

❗️Our new paper "Local activation of Cxcl12a signaling controls olfactory placode morphogenesis in zebrafish embryos" is out 👇 BiorXiv.🙏 Thanks so much to all coauthors: fantastic people ✨️fantastic work. Math modeling to understand morphogenesis. Get in touch if interessed

Come to Tokyo March 2026 for the limb conference! Honored to be sharing the keynote space with Cliff Tabin and Ken Poss.

🎉 We're excited to share our new research in @Nature! We reveal that crocodile head scales self-organize through compressive folding of the skin - a mechanical twist on their development & evolution! Please read & share 🐊🔬 @genevunige @UNIGEnews nature.com/articles/s4158…
