Excited to share the first preprint from my PhD at @binfutrecht.bsky.social ! 1.5 years ago, @bramvandijk.bsky.social hired me to investigate: why do prophages preferentially carry virulence genes? Using mathematical models, we propose that spatial structure plays a key role. Here's a summary:

Excited to present work from my preprint at #SMBI2025 @uni-jena.de on September 18th. I will be speaking on how spatial structure can explain the association of microbial accessory genes with inducible prophages.

The first paper of my PhD is now available as a preprint! 🎉

Transposable elements (TEs) don't just jump within fungal genomes, they also move extensively between species. In this study, we screened over 1,300 fungal genomes and found a conservative estimate of 5,500+ horizontal transfer events.

🚨 Now that @sultannazir.bsky.social has written about his work, let me try and summarise what we found. The question we worked on was inspired by Takeuchi et al. (2023) pubmed.ncbi.nlm.nih.gov/37339743/, who illustrated that (pro)phages are enriched in virulence factors compared to plasmids. [1/10]

We did it! We caught Starship #transposons moving between #fungal species in the lab, including between species separated by ~100my. We think Starships are a mediator of HGT in fungi, akin to conjugative elements in bacteria. Check out the preprint. www.biorxiv.org/content/10.1...

Okay… I gotta mute this one. It’s getting a bunch of replies about how it’s not worth explaining true things because “the right is stupid”.

I want us all to reflect on the reality that calling working class Americans stupid only benefits people who stand to gain from a divided working class.

Large crowds mobilising today to protest (we could not even fit in 3 different trains) in The Hague.

The Dutch government wants to cut 1 billion euros to science and education. This policy will damage the country profoundly.

Stop the budget cuts.
Protect the future.

@woinactie.bsky.social
All the trains towards the protest against the budget cuts were full, so we’re taking a detour in this relatively empty train.

This plan will not save money. This plan will cost money. It will cost - EVERYONE - money.
