Moritz Kramer & colleagues discuss global approaches to infectious disease analysis and modelling, emphasizing federated approaches and addressing challenges in data interoperability, equity, & trust. Part of our Focus issue on #infectiousdiseases.

"Tell me who your friends are, and I’ll tell you who you are." It turns out, microbes follow the same rule! Very proud to share our lab's new paper in @natmicrobiol.nature.com showing that bacteria don't just respond to their environment, they respond to each other. www.nature.com/articles/s41...

Very pleased to see this work published. We analysed the oral microbiomes of children with noma and found that previously uncharacterised Treponema bacteria were both prevalent and highly abundant. journals.plos.org/plosntds/art...

Including the old black cat adoptions survival analysis example as a case study in the forthcoming Bayesian Workflow book. This is presented as a whole incremental workflow with simulation, validation, and model comparison. Just now went through code and extra-commented and cleaned. Getting close!

We're doing the final sprint, and I think we're able to send the PDF of the forthcoming Bayesian Workflow book to the publisher in the next two weeks (500+ pages), which would mean it would be published some time next year
