Our review is out in Nature Reviews Genetics! rdcu.be/d5AY2
We show how phylogeny-based methods can resolve the problem of non-independence in genomic datasets.
These methods must be considered an essential part of the comparative genomics toolkit.

I thoroughly enjoyed visiting the @biology.ox.ac.uk department - thanks so much for hosting me @annadewar.bsky.social !
And thanks to everyone who chatted to me about plasmids, genomes, and more.
I even manage to find a phage in the natural history museum before leaving :)

Great to have Dr David Sünderhauf visit Oxford over the past couple of days!
A really nice talk on competition between plasmids carrying CRISPR-Cas and Toxin-antitoxin systems. Theory, experiments and bioinformatics all in one project!
