Very excited that my final postdoctoral work is now online in Cell @cellpress.bsky.social.

Using 16 (!) cryo-EM structures, we uncovered how the three proteins coronin, cofilin and AIP1 work together to rapidly disassemble actin filaments.

🪼 How did the animal body plan evolve?
This ‘fundamental’ study in Clytia sheds light on how Wnt3 coordinates both gene expression and planar cell polarity during axis formation, offering key insights into the origins of morphogenesis.
