Delighted to see our paper studying the evolution of plasmids over the last 100 years, now out! Years of work by Adrian Cazares, also Nick Thomson @sangerinstitute.bsky.social - this version much improved over the preprint. Final version should be open access, apols.

Excited to share a new preprint w/ the Sonnenberg lab, led by Matt Carter, @zzzhiru.bsky.social & @mattolm.bsky.social. We analyzed the microbiomes of two non-industrialized populations from opposite sides of the globe to try to reconstruct the recent evolutionary history of our gut microbiota.
Prehistoric Global Migration of Vanishing Gut Microbes With Humans
The gut microbiome is crucial for health and greatly affected by lifestyle. Many microbes common in non-industrialized populations are disappearing or extinct in industrialized populations. Understand...

Super excited to share my latest preprint with @klohmueller.bsky.social! Here we leverage the unique signature that recessive deleterious variants can lead to an increase in archaic ancestry to tackle a classic question - the dominance distribution on the human genome www.biorxiv.org/content/10.1...
Neanderthal introgressed ancestry reveals human genomic regions enriched with recessive deleterious mutations
Negative natural selection on deleterious mutations plays a key role in shaping human genetic variation. Understanding the dominance of deleterious mutations is critical as it can fundamentally impact...

Excited (and relieved!) to share that my 1st paper in grad school finally came out in PLOS Biology! We were motivated by a very basic question: how fast, really, do bacteria exchange DNA in the human gut? (1/n)
Dynamics of bacterial recombination in the human gut microbiome
Recombination is a ubiquitous force in bacterial evolution, but its dynamics are poorly characterized in many natural populations. This study presents a metagenomic approach for quantifying the landsc...
