Very pleased to finally share the main story from my PhD, now published in @natcomms.nature.com ! 🎉 Using a sea anemone we discovered and characterised epithelial cell extrusion as the mechanism underlying starvation-induced cell loss. 🔗 Open-access article: www.nature.com/articles/s41...

Epithelial cell extrusion underlies starvation-induced cell loss in a sea anemone - Nature Communications

Epithelial cell extrusion in a sea anemone shares key hallmarks with bilaterians and is dynamically regulated by nutritional status. During starvation-induced body shrinkage, extrusion likely contribu...

Paris Week from July 15-17 in Erlangen brought together researchers from Paris-based scientific institutions matched by participants from FAU, MPL, MPZPM, and UKER. They worked to establish a network of collaborations pushing the boundaries of the new emerging field of Physics and Medicine. 📸 MPL

I worked for New York’s largest medical center at the start of the pandemic. There were morgue trucks on the streets. They set up emergency medical tents in Central Park. Healthcare worker colleagues died. It is horrific that RFK Jr is on national TV lying that ICUs were empty.

Always one of the nicest cell biology conferences!

New preprint! How does a cell "know" how big to make its nucleus? This has puzzled biologists since the 1800’s. We show the answer is physics: colloid osmotic pressure. 🧵1/5

Amazing Paris Week in Erlangen on Physics and medicine!

What determines how epithelial cells divide when shape cues disappear? Our new work shows that division follows the axis of maximal stress anisotropy. This “principal-stress rule” links mechanics, proliferation, and homeostasis. Amazing work from @luanger.bsky.social. www.biorxiv.org/content/10.6...
