Postdoc in the Rocha Lab at Institut Pasteur. I love anything moving within and between bacterial genomes, reading old research papers and making microbiology experiments edible with sourdough baking =)

Shuttling, swapping, and mixing: the rapid modular evolution of antiviral repertoires in temperate phages and their satellites
Abstract. Interactions between bacteria, bacteriophages, and their satellites are shaped by a myriad of defence and counter-defence mechanisms. Here, we id

Horizontal gene transfer is often depicted as a process distributing pre-existing functions to novel genetic backgrounds. Yet HGT can also increase the rate of functional innovation after transfer. Here's a brief review on the topic: ecoevorxiv.org/repository/v... #evosky #microsky

DoxyPEP has been implemented in several countries as a public health intervention against bacterial STIs, but plasmids in Neisseria gonorrhoeae undermine its promise. We summarise knowledge of gonococcal plasmid biology and epidemiology to address this threat. journals.asm.org/doi/10.1128/...

➡️ preprint from the lab! Bacteria have loads of antiviral defences in their mobile genetic elements (MGEs). So when MGEs move between bacteria, the defences move with them, generating a fast turnover of defences in bacteria. But what about the antiviral defence turnover in the MGEs themselves? 🤔 🧵👇

Bacteria chromosomes contain Genomic Islands that provide virulence, antibiotic resistance, MGE-defence,... They transfer between cells, but the mechanism of most remains elusive. Here we explore the conjugative capacity of these mysterious Genomic Islands. www.biorxiv.org/content/10.6...

Neisseria gonorrhoeae carries an unusually large number of restriction–modification systems (up to 16!), many of which are phase-variable. How does this affect plasmid transmission in gonococci? doi.org/10.64898/202...

On Friday, I passed my PhD viva with no corrections. I can't believe it has already been 4 years at @dunnschool.bsky.social @ox.ac.uk ! What an amazing time it has been! A huge thank you to my supervisor Prof Christoph Tang who has supported me throughout my PhD journey!

It started with a passionate discussion about #GenderEquality in science on a trainride and suddendly, we have been running panel discussions for over a year. In our last panel, I discussed with Dessislava Veltcha, Sally Cowley and Mathew Stracy how to navigate different career paths.
