Great collaboration with @guo-lab.bsky.social to determine an in situ architectural model of the Tad pilus machine. Be on the lookout soon for a preprint on the same topic by Grant Jensen and @viollierpat.bsky.social. #microsky
As mentioned, here is the preprint by Jensen and @viollierpat.bsky.social on the in situ structure of the Tad pilus. www.biorxiv.org/content/10.1.... Nice work and great to see that we are seeing the same thing! Our preprint: www.biorxiv.org/content/10.1... #microsky

Congratulations Marie! Immensely proud! Looking forward to seeing where you take your project on evolution of bacterial elongation.
Excited to share that I have been appointed F.R.S.-FNRS Research Associate to launch my independent research group at the University of Namur!
We will study the diversity, regulation & environmental control of bacterial cell elongation.
More soon- new projects, collaborations & opportunities ahead!

Excited to see our automated HT growth/microscopy screening platform coming together. Pictured: the intermediate version to screen 5-10,000/day unattended. Diagrammed is the full platform due next summer after renovations @ 20,000/day and integrated with our colony picker.

Great to see @ianyyen.bsky.social's first paper in print! He deserves major congratulations for driving a stimulating collaboration: he determined structures of the Tad pilus ATPase CpaF from Caulobacter and proposes how CpaF employs a rotary mechanism of catalysis to drive pilus assembly #microsky

This is why the new threat against university funding in Canada is concerning, clearly a fraction of the population here do not understand either how things work and universities contribute.
