Finally out! 🎉 After 3 years of postdoc in London, here is my main work, now published in Nature Comm. (and as co-corresponding author!) Using a combination of bioinformatic and experimental approaches, we propose a model of plasmid evolution in Staphylococcus. www.nature.com/articles/s41... ⬇️ 1/4

Mobile genetic elements drive a plasmid fusion and deletion lifecycle shaping evolution and antimicrobial resistance - Nature Communications
Plasmids drive bacterial adaptation, but how their diversity arises has remained unclear. Here, they show that in Staphylococcus aureus, mobile genetic elements repeatedly fuse and delete plasmids, re...

A systematic identification of resistance determinants to antisense antibiotics suggests adaptation strategies dependent on the delivery peptide - Nature Communications
In this study, authors investigate the evolution of bacterial resistance to antisense peptide nucleic acid (PNA) antibiotics. They observe that this typically occurs mainly by reducing drug uptake via...

Projects working with Helen Alexander www.pnas.org/doi/10.1073/... and Raf www.nature.com/articles/s41... inspired me to think about this problem and I look forward to hearing your thoughts #microsky PS: I also don't think that heteroresistance is real

Our paper on the YprA family of helicases and their roles in bacterial defence is now out! We describe ARMADA, a defence system synergise with Druantia and show that both systems spread horizontally on a novel type of mobile genetic element that we call SPIDERs www.sciencedirect.com/science/arti...

Happy to share that our latest research on the eco-evolutionary dynamics of MDR plasmids and PDPs is now out (open access vAuthor) in The ISME Journal doi.org/10.1093/isme... Here, we explored how plasmid-dependent phages (PDPs) act as a selective pressure against the spread of multidrug resistance
