It’s out! 🐟 We compared three regeneration superstars—axolotl, zebrafish, and Polypterus—to ask how animals regrow limbs and fins. We find shared core processes, and other programs fine-tuned by evolution in surprising, lineage-specific ways. tinyurl.com/mpftkn7y

Last Friday I successfully defended my PhD thesis! Thank you to all who attended, in person and virtually! Thanks to my partner, family and friends for their endless support, and a thank you especially to my mentor Sarah McMenamin for her guidance and encouragement all these years.

New preprint up with collaborators Jianguo Lu, @mpodobnik.bsky.social, Uwe Irion, Braedan McCluskey, John Postlethwait and others. New Danio genomes, evolution and pigment pattern variation. Long time in the making www.biorxiv.org/content/10.1...

transport yourself to the late 90s with this really cool paper on digit number regulation by Shh and BMP, ZPA and AER. www.pnas.org/doi/10.1073/...

Are digits modified fins, or evolutionary innovations? Read how we tackled this old question from a new angle🧪 A story with @chasebolt.bsky.social, @homeobox.bsky.social and myself, coordinated by @denisduboule.bsky.social from @college-de-france.fr and published in @nature.com today! #InHoxWeTrust

What guides fibroblast precursors' migration from the #sclerotome during vertebrate development? @penghuang031.bsky.social &co show that this is driven by #PDGF -mediated chemoattraction, enabling their differentiation into specialized #fibroblast subtypes @plosbiology.org 🧪 plos.io/3HTZ92Y

We take for granted that our hands have two sides and can articulate in an endless number of ways. But what about a fish’s fin? Can a fish know something “like the back of its fin,” or have its future told with a fin palm reading? Check out this bluetorial to find out 👇🧪🧬🐟 doi.org/10.1101/2025...

Hello Bluesky: Long time listener, first time poster! Excited to share the first publication of my Ph.D. work studying the development of appendage shapes in @plosbiology.org! The zebrafish caudal fin is quite distinctive, and we examine the timing and mechanisms of how its shape might come to be!
