Geomicrobiologist 🌋 at @embl.org studying extreme microbial ecosystems in the Central Andes
Last week I attended the M-FED 2025, where I presented the discovery of uncharacterized microbial ecosystems in the Central Andes 🌎
I also joined the workshop “Grow your own microbial mat” and we visited the UNESCO Geopark Heeseberg! ⛏️
A great week of microbialite science!

Some years ago, we discovered a modern microbialite reef under conditions resembling primitive Earth 🌋
Now we show how seasonal extremes drive microbial shifts and mineralisation, offering a window into processes that shaped Earth’s first biostructures 🪨

I recently participated in the GRC on Applied and Environmental Microbiology 🦠, where I had the opportunity to serve as a Discussion Leader and to present my work on modern microbialites as a Speaker.
Many thanks to the chairs @deniseakob.bsky.social, Marianne Haines, and @jlrolando.bsky.social!

We’ve uncovered Asgard chromatin structures formed by a Hodarchaeal histone : closed hypernucleosome conserved in archaea and an open form resembling the H3-H4 eukaryotic octasome. Fantastic work by @harshranawat.bsky.social!

The Chamber of Secrets has been opened... but for yerba mate! 🧉 🧬
Combining genomics, biochemistry, structural biology, and ancestral sequence reconstruction, we characterized how yerba mate synthesizes caffeine differently from coffee and tea plants 🌱 #yerbamate #caffeine #science

🧉 #YerbaMate makes the third most popular caffeinated drink in the world, but it’s unrelated to tea and coffee. The first reconstruction of its genome is helping us understand how multiple species have evolved to synthesise caffeine.
