Super proud to be part of SFB1348 — and excited to share that I now officially have my own lab in Münster! 🎉🪰
We’ll study #cellbio & #morphogenesis, focusing on organ sculpting and #chirality in #Drosophila.
I’ll soon hire my first #PhD student — feel free to reach out!

I tried an even harder example on Gemini Pro image generation and this is quite scary/amazing. I asked for a microscopy image of around 20 HeLa cells, GFP tagged 20% nuclear, 10% membrane, +1 nuclear staining, + overlap. Image below and prompt in the following post.

Hey #Drosophila evolution people, quick phylogeny question! Is this simplified tree reasonable? I integrated multiple papers & added some polytomies, so that there is nothing too speculative in there. Does it look right to you? 🪰 It's just for a presentation 😉

If you’ve ever wondered why you can inject things into the yolk early and it affects the embryo, this phenomena is the reason it works! 👇 #zebrafish

Cryosection of 5dpf old 🦓🐟 larvae showing:

🟢VitaminD-binding protein-GFP
⚪Phalloidin
Notice how there’s no GFP signal in the pronephric duct — proof that filtration barrier is working perfectly

@sushantbangru.bsky.social and @rdiegmiller.bsky.social new review on regeneration is out in Nature Reviews Molecular Cell Biology. A fun piece to write and another great collaboration with @kenposs.bsky.social.
New Online! Signal control during tissue regeneration in adult animals
Signal control during tissue regeneration in adult animals
Nature Reviews Molecular Cell Biology, Published online: 11 November 2025; doi:10.1038/s41580-025-00917-1The ability to track single cells in vivo, combined with insights into chromatin structure, immune–tissue crosstalk, bioelectric and metabolic cues and quantitative modelling, is changing our understanding of how tissues are repaired and renewed. This Review discusses how signals are regulated during regeneration and future directions for a more quantitative understanding of regenerative biology.
