We wrote a method paper on our different microfluidic technologies to confine microbial cells, and display a novel and unique device to confine and even retrieve cells to perform, for instance, omics analysis on confined cells! Reach out if this is of interest for your research.

Our collaborative paper, with Daria Bonazzi and @dumenillab.bsky.social is finally out in Nat Comms! Using microfluidic confiners, amazing Laure Leblanc found that confined growth of E. coli uncouples growth and division, as well as pressure and biomass production. tinyurl.com/4zdwrp39

Bacterial growth under confinement requires transcriptional adaptation to resist turgor pressure build-up

🔬🧪🦠 An exciting opportunity to work at the interface of Fungal Cell Biology & Biophysics in Nice, FR in a collaborative project on roles of cytoplasmic crowding in fungal pathogen morphogenesis, antifungal responses and host interaction.

Please save the date: The Microphysio Conference is back and will be held in Cargèse from April 25th to April 30th!
With a great lineup of speakers, it’s an excellent opportunity to exchange ideas in fields related to organ-on-chip, organoids, bioprinting, mechanobiology, and much more!
Stay tuned.

#ResultatScientifique🔎| Quand Candida albicans réduit ses ribosomes, ses cellules deviennent plus fluides, ce qui l’aide à changer de forme et à mieux infecter l’organisme 🍄

Happy New Year! And happy to share our latest instrumentation work, led by fantastic Ines Muguet. Ines showed that sliding elements, developped by Ben Meriem et al, can be functionnalized to have electrodes, thus allowing reconfigurable electrochemistry-on-chip! Stay tuned, more preprints to come.

📢 New extended abstract submission deadline: 6 January 2026! Outstanding speaker list, plus many slots for short talks by students, postdocs, and junior PIs. Join us in March in Barcelona! events.ibecbarcelona.eu/embl-ibec-co...

Wonderful collaboration with @robertarkowitz.bsky.social et al! Fascinating result that inhibiting ribosome biogenesis triggers filamentation of C. albicans!

New preprint from the lab, an old work from Z. Ben Meriem! We compress cells in 2D and show that proliferation and motility decrease. Crowding increases under pressure, which may explain this result. Interestingly, more mesenchymal cells seem to be more sensitive to pressure!

I want to share three reviews on crowding and spatial confinement, active areas of research on our end:
- on the dynamic structure of the cytoplasm: tinyurl.com/4d6drhnv
- on the sensing of and response to crowding: tinyurl.com/959ht4fw
- on the effect of spatial confinement: tinyurl.com/nhh7sk9w

Happy to bring this to light!
The result of quite a few years and fabulous collaborations with wonderful colleagues! Thread from Antonio Serrano (@antonioserrano) coming soon!

Pre-announcing the EMBO/EMBL symposium "Mechanobiology Across the Tree of Life", Heidelberg, 9-12 June 2026. It is still very very far away, but save the date 🗓️. With Alba Diz-Munoz, @nicolettapetridou.bsky.social , Kirsty Wan @micromotility.bsky.social, Enrique Rojas.
