I am happy to share that my NWO Veni project was awarded 🍄🧬🔻! In this project, I will study how transposons shape genome folding, evolution, and adaptation in a fungal salamander pathogen. I am incredibly thankful for all the support and look forward to this next chapter #fungi #transposons #TEsky
I am very excited to share that I have received a Veni grant from the Dutch Research Council to start my own line of research on archaeal evolution at the Royal Netherlands Institute for Sea Research! www.nioz.nl/en/news-and-...

Excited to share our new preprint led by Fred and me in collaboration with the archaeal community! We found that the molecular foundation of histone-based chromatin has pre-eukaryotic roots in Asgard archaea. (1/4) #ArchaeaSky www.biorxiv.org/content/10.6...
Emergence of histone-based chromatin complexity in Asgard archaea
The emergence of the eukaryotes coincided with the diversification of histone proteins and their post-translational modifications by enzymes that constitute the core of eukaryotic chromatin. Yet the e...

Our paper "Gene ancestries reveal diverse microbial associations during eukaryogenesis.” is finally out in Nature. Eukaryogenesis was likely a gradual process shaped by multiple microbial partners and virus-mediated gene transfer, rather than a single binary symbiosis. doi.org/10.1038/s415...
Dit is het gevolg van onafgebroken ophitsen door extreemrechtse groeperingen. Crimineel gedrag dat je niet af kan doen met zogenaamd ‘legitieme zorgen’. Het is een directe ondermijning van onze democratie. En bovendien levensgevaarlijk. nos.nl/artikel/2614...

🧵 1/10 New paper out in @natmicrobiol.nature.com from my postdoc at @mib-wur.bsky.social! 🎉 How eukaryote-like was the archaeal ancestor of eukaryotes? Sequence searches alone can't tell us — so we used protein structure prediction to look deeper. 🧬 www.nature.com/articles/s41...
Prediction of eukaryotic cellular complexity in Asgard archaea using structural modelling - Nature Microbiology
A structural catalogue of the Asgard archaeal pangenome reveals hundreds of eukaryotic-like proteins that suggest a higher degree of cellular complexity in the archaeal ancestor of eukaryotes.

Just over ten years after the discovery of the first Asgard archaeal genomes, we revisit the rapid expansion of this remarkable archaeal lineage. From diverse genomes and metabolisms to eukaryotic signature proteins and the first cultured representatives. www.nature.com/articles/s41...
