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/ www.science.org/doi/10.1126/...
Intracellular competition shapes plasmid population dynamics
From populations of multicellular organisms to selfish genetic elements, conflicts between levels of biological organization are central to evolution. Plasmids are extrachromosomal, self-replicating g...

Our latest paper is out with @adiop.bsky.social and @gmdouglas.bsky.social. We analyzed the extent of homologous recombination between bacterial species (introgression) and how it affects species borders (it can vary a lot depending on the approach used to classify species!). rdcu.be/eQAMf
Introgression impacts the evolution of bacteria, but species borders are rarely fuzzy
Nature Communications - It is commonly thought that bacterial species borders tend to be fuzzy, due to frequent exchange of DNA. Here, Diop et al. quantify the patterns of gene flow between core...

Congratulations to Joe Felsenstein on being awarded the 2026 Mendel Medal!
“The prohibited activities would include joint research, co-authorship on papers, and advising a foreign graduate student or postdoctoral fellow. The language is retroactive, meaning any interactions during the previous 5 years could make a scientist ineligible for future federal funding.”

Hey Bluesky! 👋 I’m a bioinformatician (PostDoc, University of Manchester 🇬🇧) fascinated by eukaryotic & prokaryotic #genomics, #transcriptomics, and molecular #evolution. I’m exploring new opportunities in the UK — let’s connect!
Sofya is a fantastic scientist and a super nice person. Definitely recommend finding a way to work with her!
hey bluesky 👋 visa hurdles mean I’m looking for opportunities outside the US. I’m a computational biologist (bacterial + phage genomics, postdoc in Koonin’s group @ NIH). I am interested in teaming up on funding apps. reach out if this resonates!
NEW PAPER! Some kinds of genetic mutations are more likely to arise than others. Such "biases" in mutation vary between species. Analyzing data from 14 species, we show that this variation explains species differences in the genetics of adaptation! (1/3) www.biorxiv.org/content/10.1...

Sometimes we’re unsatisfied with a thing we made because when it only existed in our head, we saw all the things it could have been and when it’s done we know all the things that it isn’t, but we can’t see the way it expands into a million new things when someone else unpacks it in their head. 🖊️🦑
Dierks et al. engineered an replisome that replicates only target plasmids at mutation rates 100,000 times higher than normal but leaving the rest of the genome unchanged. They evolved TEM-1 β-lactamase to gain strong resistance to several antibiotics in under a week. www.science.org/doi/10.1126/...

New paper alert! 🚨 Plasmids promote bacterial evolution through a copy number-driven increase in mutation rate. We combine theory, simulations, experimental evolution, and bioinformatics to demonstrate that mutation rates scale with plasmid copy number. Let's dive in! 🧵👇
Plasmids promote bacterial evolution through a copy number-driven increase in mutation rate
Plasmids are autonomously replicating DNA molecules that stably coexist with chromosomes in bacterial cells. These genetic elements drive horizontal gene transfer and play a fundamental role in bacter...

Super cool talk by Parker Crossland showing that DNA in single fixed cells can be amplified & sequenced (B. subtilis, E. coli & yeast). Only 14 cells needed to cover the full yeast genome 🤯 Adding barcodes captures rare genotypes missed by colony picking 🦠 Preprint 👇🏽 #SMBE2025
Aerobic bacteria show higher A>G (and lower G>A) mutation rate than anaerobes. First results in bioinformatic project to estimate mutation spectra across bacterial tree under my supervision. Qs and ideas are wellcome. #SMBE2025
