Interested in predicting the dynamics of antibiotic resistance? Come work with us! We're looking for two postdocs to develop predictive models of resistance. We're interested in a range of approaches (mathematical & statistical modelling, causal inference, machine learning).

New paper: mechanisms that maintain diversity in bacterial genomes also play a role in organising it.
This paper combines two of my favourite topics in bacterial evolution: NFDS and strain structure.

We are pleased to share our last article rdcu.be/fabhM. It offers the most comprehensive analysis so far of Ab+non-Ab resistance genes in human gut microbiome, using an Indigenous population (low industrialization, chronic Hg exposure from gold mining) 6/6👇
New preprint on the limits of detecting higher-order interactions in microbial communities.
www.biorxiv.org/content/10.6...
We find that the dominance of additive and pairwise interactions on community function may not reflect biological simplicity, but fundamental limits of statistical detection.
New preprint out on bioRxiv!

Can conjugative plasmids be used to control plasmid and pathogen spread?
Follow me down the rabbit hole that led to this story 🧵
New pre-print with @wtmatlock.bsky.social!!!

What shapes the distribution of plasmids across bacteria? Our paper shows that conjugative plasmids actually have a very narrow distribution compared to mobilizable plasmids. Conjugative systems restrict plasmid transfer!

What a fantastic new addition to my lab! 🚀
Welcome @albertohca.bsky.social to the @uam.es family! Stay tuned for the science we’re going to build together in the coming years!
A short research stay in 2019 (back in the pre-COVID era) at José R. Penadés lab turned into the third chapter of my PhD and today it finally sees the light.
How does population density affect evolutionary trajectory?
Microbes construct their own niche which in turn reshapes their evolution.
Preprint drop from grad student @noahhoupt.bsky.social whose evolution experiments featured blue/white colonies, 1000 generations, a lab move, and much more!

🧬New paper out! We report the first isolation of viable B. bacteriovorus predators from human gut microbiota. www.frontiersin.org/journals/mic.... Great work of Mario Romero @migueldiezfdz.bsky.social @josete600.bsky.social and @rosacampo.bsky.social
Pictured is a map of plasmids, which are DNA molecules that can be transferred between bacteria. Each ring and dot represents an evolved plasmid and a mutation, respectively. Image credit: Paula Ramiro-Martínez.

New paper out in PNAS!!! 🎉
Do more plasmid copies mean faster evolution?

New paper out in @pnas.org, and it made the cover! 👁️
We represent plasmids as circles and mutations as dots, resembling an eye, because in this paper we literally 𝑤𝑎𝑡𝑐ℎ plasmids evolve.

Application deadline for this postdoc position in my group closing next week 🦠 thank you all who have shared so far!
Lab ready. Looking forward to what comes next here.
New preprint out! 📣🚨
We found that loss-of-function mutations in the carbapenem entry porin OprD of Pseudomonas aeruginosa do more than confer #AntibioticResistance: they reshape the bacterial membrane and interaction with the host, enhancing epithelial colonization capacity 🦠

I’m excited to share this article from my PhD, exploring the role and prevalence of peptide deformylases! It has been a truly enriching and fascinating scientific journey. Thank you, @amazeld.bsky.social, for welcoming me into your lab and giving me the scientific freedom to follow my curiosity!
Our story on plasmid streamlining is now published in PLoS Biology! With @andrewmatthews.bsky.social and @sonjalehtinen.bsky.social

I'm so happy that I can finally share the results of my first postdoc paper with @baym.lol!!! Turns out plasmids are an amazing system to study multi-scale evolution and we can track within-cell and between-cell dynamics!

Hot off the press! Our latest paper led by @fernpizza.bsky.social, understanding how plasmids evolve inside cells. These small, self-replicating DNA circles live inside bacteria and carry antibiotic resistance genes, but also compete with one another to replicate. 1/

Enhorabuena!! 👏🏼👏🏼
2/ 🤝 This project is carried out at @cnb-csic.bsky.social is conducted in consortium with @tmcoque.bsky.social (Instituto Ramón y Cajal de Investigación Sanitaria).
1/ Antibiotic resistance causes ➕ than 1 M deaths each year and understanding why this happens is key to stopping it.
With #HealthResearch support, @sanmillan.bsky.social is investigating how different plasmids (DNA fragments) coexist in bacteria and confer resistance.

New paper out 🎆 When an antibiotic-resistant E. coli strain lands in our gut microbiome, whether it will get established or not depends on the ecological context. We studied how other microbes, nutrients, and antibiotic exposure shape its fate.👇
Can we leverage bacterial competition for targeted replacement of harmful strains? Maybe! Our recent piece in @natmicrobiol.nature.com provides a theoretical framework and a set of experiments to show what it might take: www.nature.com/articles/s41...
Our paper “Global dissemination of npmA mediated pan‑aminoglycoside resistance via a mobile element in Gram‑positive bacteria” is now in @natcomms.nature.com. Part of my freshly defended PhD, so doubly happy! 😄🎉
