Interested in doing a PhD in tumor mechanobiology?

At Université Paris-Saclay, the upcoming PhD selection process is open, and I’m looking to put forward a candidate to join my lab.

If you’re excited about uncovering how mechanical signals regulate tumor progression, please get in touch!

I’m thrilled to share that I will join @gustaveroussy.fr as a Group Leader!

Our objective: to understand how mechanochemical feedbacks regulate tumor dynamics and plasticity, with the overarching goal of bridging tissue mechanobiology and tumor pathophysiology using human organoids.

Writing is how science thinks.
Editors help that thinking become clear and coherent in journals.

Writing is where scientists and editors meet.

Worth reading ⤵️

How can cells use information from neighboring cells to improve the spatial precision of morphogen patterns? 🤔

We show that cells can gain positional information by "talking" to their neighbors - how much depends critically on spatial correlations of the patterns.

Curved Microfluidic Confinement Reveals Cell-Shape-Dependent Nuclear Mechanotransduction in Adaptive Migration Cells navigate within diverse curved microenvironments derived from extracellular matrix (ECM) and neighboring cells in vivo. While current studies primarily focus on cell migration on curved surfaces...

Cells navigating microscale curved environments stretch their nuclei, triggering the membrane stretch-sensitive cPLA2 pathway, which in turn rewires cell signaling and morphodynamics to propel the cell forward and avoid steric hindrance pubs.acs.org/doi/10.1021/...

Linking molecular tension and cellular tractions: a multiscale approach to focal adhesion mechanics - Communications Biology Simultaneous mapping of tractions and molecular tension reveals how cells coordinate forces across scales, from whole-cell mechanics to polarized force transmission within individual focal adhesions.

📝Check out our latest paper published in @commsbio.nature.com !!

Great work by Samet Aytekin and Laurens Kimps in this collaboration with @rochalab.bsky.social where they combined simultaneous FRET tension sensors and traction force microscopy!

I'm very happy to share my first article as a corresponding author published in @natmethods.nature.com !! 😍

Some groups (like us) have developed complex 3DTFM methods in the last 15 years.

BUT its usage in studies that help better understand disease or development has been almost non-existent.

I will be recruiting two postdocs early next year.

- one biologist interested in working on lymphatics!

Reach out if you are interested 👍

I am putting together a collection of video-protocols we (will) use in tissue mechanics research🌀
I hope to help consolidate established methods, but also showcase a few up-and-coming ones in our blooming field.
Abstract submission by March 2026! Get in touch✨

Talin force coupling underlies eukaryotic cell-substrate adhesion - Nature Communications Talin is a well-known regulator of cell adhesion and intracellular force transmission in animals. Here, the authors demonstrate that talin’s mechanical function is evolutionarily conserved and already established in unicellular eukaryotes.

Talin didn’t evolve for integrins... integrins evolved for talin 🤯

pN force coupling via talin is ancient, conserved from amoebae to humans; signaling came later.

Your periodic reminder that science is not done by a few selected "stars scientists". Science is done by hundred of thousands. Siloed money mean a few flashy discoveries and a lot of waste. Want to change things? Make funding accessible and stop funding calls with less than 2% success rate.

Ten years ago, I saw a paper with some data that has bothered me ever since: B cells in a 0-100 ng/mL gradient of CCL19 are attracted to CCL19, but B cells in 0-500 ng/mL are repelled (see movie, ignoring the big clusters for now!). Why? Here's our model! doi.org/10.1101/2025...
