Previously we had shown that axolotl tail regeneration occurs in the absence of somitogenesis. In the updated manuscript we propose that vertebral segmentation during tail regeneration occurs through a process of buckling instability. www.biorxiv.org/content/10.1...
Looking forward to sharing my postdoctoral work in just a little over a week at the UCAM Morphogenesis Series! 🐟🔬🔦

Using fluorescence live imaging and an in vitro implantation model, we show that human embryo attachment begins with direct cell fusion via syncytin-2–MFSD2A interaction.

Happy to share our new work from my graduate lab: DynamicAtlas, a morphodynamic atlas of Drosophila development! We develop methods for morphological time alignment of live data. Surprisingly, we find that the kinematics of fly morphogenesis are *very* simple. Enjoy!

zSwim, the zebrafish lab management software we’ve been developing is now officially listed in Duke OT&C’s technology portfolio! We’re launching an official Duke pilot in March 2026 at the new Ze-Core facility! If you’re in the zebrafish community, check it out!

New paper alert! We report that #zebrafish endodermal cells use contact inhibition of locomotion as a dispersal and spacing mechanism. It’s a neat example of large-scale patterns emerging from local interactions using a simple set of rules. Summary in the thread below 1/9

There’s a sizable group that protests every Friday at a local park in my home town. So of course I had to join my mom when I was home last week!
A true testament to how community-level organization can be a powerful act of resistance in current times!
Also shoutout to my former colleague @priyomadhyapok.bsky.social who took home a poster prize for her beautiful work on notochord segmentation 👏
Had an awesome time at IZFC this year in Madison! The zebrafish community is simply the best 🧬 🐟🔬
30% budget cut for NIH plus whittling into down to 8 institutes.
