Preprint alert📢! 
Ever wondered how much bacterial parasites influence evolutionary outcomes of their host? ➡️ We co-evolved two bacterial strains in conditions in which the costs and benefits of prophage carriage varied Here is what we found.

How do bacteria choose what type of defences to use against phages? We explored that question in the last paper I worked on as a postdoc at the Uni of Exeter @uniofexeteresi.bsky.social with Stineke van Houte, Stefano Pagliara and Edze Westra (not on Bluesky) doi.org/10.1098/rstb...

Can CRISPR-Cas systems target any phage? Yes, no, it depends? What does it depend on? The second paper from my PhD came out today in a special issue of Phil Trans B on the ecology and evolution of bacterial immune systems doi.org/10.1098/rstb...

PhD opportunity, please share: We are looking for a prospective PhD student to start in October 2026 who is excited about bacteria (Klebsiella pneumoniae), how they interact, and how they exchange DNA. All details can be found on the funder website 👉 gw4biomed.ac.uk/developing-c...

The team is growing fast! 🎉 Congratulations to Léa Masson on receiving a PhD fellowship from the BSB doctoral school @universitetoulouse.bsky.social 👏 The PhD will be co-supervised by @benoitjpons.bsky.social and myself - @cbitoulouse.bsky.social #PhD #Microbiology #Klebsiella

Had an amazing time at @cbitoulouse.bsky.social! Stimulating discussions, insightful questions, and always a joy to reconnect with old friends and colleagues! Thanks for the invitation @benoitjpons.bsky.social @olayarendueles.bsky.social

Great talk today @cbitoulouse.bsky.social from @annechevallereau.bsky.social- on the importance of surface receptors in phage adsorption and of intracellular phage defense mechanisms - and the relative importance of each of them in shaping phage host range &productive phage infection 🦠

Would you like to see @biorxivpreprint.bsky.social add a share to blue sky button?! I know I would! Share this post to let @richardsever.bsky.social @erictopol.bsky.social and others at bioarxiv know!

Looking for a PhD in phage ecology, metagenomics and defence systems? We have a fully funded PhD opportunity to join us at the University of York with great collaborators. See here for more info: www.findaphd.com/phds/project...

Lovely day @ CBI with our newest team members already working hard in our brand new lab. Check out the incredible #BlueSky in #Toulouse #MicroSky

I'm recruiting a Research Technician to work on plasmid transmission and antimicrobial resistance in St Andrews, to start in October. Deadline for applications is 19 June. Please share! www.vacancies.st-andrews.ac.uk/Vacancies/W/...

Just out in The ISME Journal, a paper from my time in the Westra lab. We find that the extent of phage exposure shapes subsequent resistance dynamics over longer timescales (up to 30 days). And huge thanks to first authors @bridgetwatson.bsky.social and Loris for mammoth experiments!
