New paper alert! We used our fav technique, genetic suppression, to understand how FimX controls function of the T4P PilB motor ATPase in Pseudomonas aeruginosa. Great collab with the Ellison lab at U Georgia who helped with some fancy microscopy to capture pilus dynamics! doi.org/10.1371/jour...

All science arises only because of the shared broader community. I want to especially recognize Rotem Sorek @soreklab.bsky.social Aude Bernheim @audeber.bsky.social our collaborators and the many wonderful labs and scientists in the field bringing together human and bacterial antiviral research!

Congratulations to Philip J. Kranzusch, Ph.D., Professor of Cancer Immunology and Virology, who was one of three scientists awarded top honors at the 2025 Blavatnik National Awards for Young Scientists.

Excited to be part of this collaboration with the Burrows lab exploring twitching and surface surface sensing by P. aeruginosa. This work further delineates a role for the T4P motor proteins and pili for surface sensing.

Thrilled to be a coauthor in this story 🚀 Check out our latest publication on the archaellum - spoiler: it's an archaellum in bacteria 😱 Who would have thought? Thank you to all the authors, and especially @sshamphavi.bsky.social for really keeping this paper rotating 😉

Happy to share that our story on the bacterial archaellum was published today in @natmicrobiol.nature.com
www.nature.com/articles/s41...
