Evolutionary biologist expert in terrestrial planarians and also digging into the genomic regulation of unicellular Holozoans. Ramon y cajal researcher at the zoology section from the University of Barcelona (Spain)
Sailing in @biorxivpreprint.bsky.social ready for summer, our study on the iconic Portuguese man o' war 🪼 is out: www.biorxiv.org/content/10.6.... We use (epi)genomics to understand a critter that fascinates me since childhood. Massive team effort with @obog.bsky.social, Cummins and Neely groups. 🧵
New preprint out where I had a small contribution. Want to know more about Physalia utriculus? Take a look ! 👇 @multicellgenome.bsky.social @obog.bsky.social @alexdemendoza.bsky.social www.biorxiv.org/content/10.6...
Integrative genomics of the siphonophore Physalia utriculus reveals the regulatory logic of colonial division of labour and the molecular basis of venom activity
How a single genome gives rise to specialised multicellular individuals that function as an integrated organism remains a fundamental question in the evolution of complex coloniality. Siphonophores re...

Two former PhD students from my lab have led this great work, @martaalvarez.bsky.socialand Jordi Paps. How proud I feel, Congratulations!
Marta Álvarez-Presas@martaalvarez.bsky.social · 9mo agoHappy to share Jialin's first publication. She did a great job exploring the transition to land in animals. Co-supervised by the great Jordi Paps and me and in collaboration with Davide Pisani and @phil-donoghue.bsky.social
Pleased to be a small part of this molecular palaeobiology study by Jialin Wei, led by Marta Álvarez-Presas and Jordi Paps, with help from Davide Pisani. Animals repeatedly used similar genomic solutions to the challenges of terrestrialization @bristolpalaeo.bsky.social @bristolbiosci.bsky.social
