Great to attend the meeting of ‘Davidsonians’. Quite a few generations of grad students and postdocs. Just a fraction of the 300+ that went through his lab.

Home, sweet home…..

Here we go…. Meeting in tribute to our ‘boss’ EH Davidson.

September starts with a new challenge (stay at the level! 😀 ). Friends and students gathering for an intense science weekend. Back to Pasadena (home sweet home).

Our last baby. Acoels don’t just have brains, they also use them! @simon-sprecher.bsky.social #Nikita Komarov and #Xavier Bailly journals.plos.org/plosone/arti...

With the best ‘morphological’ company in Concepcion (Chile)

Here we go…🛫

Honored to have been selected as an Associated Member of the Stazione Zoologica Anton Dohrn in Naples. Grateful for the recognition and excited to continue contributing to the scientific community. A lot of great colleages and friends there!

Hey blueskiers! We are looking for examples of "microRNAs" that you came across in your studies that seemed weird or behaving unexpectedly.

Very sad to leave the Arctic Museum of Tromsø. This sabbatical has been unforgettable. I was incredibly fortunate to have Bastian Fromm @frommlab.bsky.social, such a fabulous teacher, host and friend during my stay. It’s hard to say goodbye to such a special place.

Hasta las narices del sistema español de ciencia y tecnologia! Fed up with the Spanish system of Science and Technology. I will happily leave it quite soon. 😤

Finally, saw the Vault in Svalvard.

I am grateful to have been promoted to the highest rank as Research Professor (ICREA) following my récent 5-year evaluation-a meaningful milestone at the end of my academic path. 🥂🥂

Flowering season at the Arctic Botanical Garden. Tromsø .Beautiful spectacle of colors.

Probably the nordernmost reader you got @maxjtelford.bsky.social (Tromso) 😉

Interested in Developmental biology? Imaging? Marine invertebrate body plans? Then this three year postdoc in my group @sotonbiosciences.bsky.social is for you! Join our team to decypher how signalling molecules shape skeletal phenotype in juvenile sea urchins. jobs.soton.ac.uk/Vacancy.aspx...

Looking for a post-doc? In the frame of the #MSCA-PF 2025 program at @sorbonne-universite.fr , the #DEEVA team (biom.obs-banyuls.fr/presentation...) from @biom-banyuls.bsky.social and @obs-banyuls.fr in #WindyBanyuls proposes a research project (www.sorbonne-universite.fr/sites/defaul...).

Got to see a copy of the doctoral thesis of zoologist, polar explorer and international politician: Fridtjof Nansen. He did his research in Bergen, on the lamprey’s nervous system, and arrived to conclusions (on neuronal connections) similar to Ramón y Cajal.(Polar Museum, Tromso)

Very nice seminar by sabbatical guest @pedromartinezserra.bsky.social on the amazing Symsagittifera acoels!

MirRNA friday meeting with the boss @frommlab.bsky.social

Good night

Got them! Done.

Arriving to work, at -7 degrees 🥶My first week in Tromso.

Tromso, new house (for a while). -6 degrees to start 🥶
