PhD candidate | Symbiont Experimental Evolution 🪰 | Interested in behaviour, evolution of insects 🐝 host-microbe interactions 🦠@iDiv & @UniHalle He/Him🌈
Had the pleasure of joining the SymbNET Summer School 2025 on Host-Microbe Symbiosis in Oeiras, Portugal 🌿🧬
A week of great talks, posters, and group projects with amazing PhDs + faculty from all over the world. Our team’s project even got 2nd place out of 7! 🎉New ideas, friendships, and inspiration

Fascinating evening at the Long Night of Sciences @idiv-research.bsky.social ! Loved engaging with kids & adults about symbionts, insects & bees 🐝 Grateful for the amazing support from the iDiv events team, colleagues & Marc Hoffmann, who educated public about German bee fauna! 🪱🐝🦋

If you’re interested in bees and their friends, do come to iDiv long night of sciences 🐝🐛🪱 there will be public education of bees and a dark room!

1/46 Hey folks, we have a new paper out on the MuLTEE. Strap in and I’ll tell you the story of how this “little paper on polyploidy” turned into the most data rich paper our lab has produced, largely thanks to the leadership and work ethic of @kaitong25.bsky.social.

Long live introverts! 😉Not the bravest mice 🐭, but the shy ones turn out to be the most persistent problem-solvers, according to a new study by the Max Planck Institute for Evolutionary Biology. mpg.de/24460941/mic... #evolution #animalbehaviour
Shy mice are more persistent problem-solvers
In a study, it wasn't the bravest mice, but rather the shy ones, that proved to be the most persistent tinkerers.

Ever wonder how to count very rare and unculturable #microbes? Our new #preprint 🥳 shows that we can use #ddPCR to count as few as 12 #endosymbiont genomes in a 20 uL reaction!🤯 Yes, this is a teaser for things to come.😉 #Wolbachia #Drosophila #SymbioSky #Entomology

Wolbachia is the most widespread animal-associated intracellular microbe, living within the cells of over half of insect species. Since they can suppress pathogen replication and spread rapidly throug...

It’s a pleasure to receive this recognition, as all the talks were truly fabulous! Many thanks to iDiv, and a special shoutout to my amazing technicians, who went above and beyond to assist me with challenging experiments and counting thousands of flies 🪰 #Spiroplasma #evolution

What happens to the #genome of #bacteria as their association with the host becomes ever more intimate?🧪🦠

A lot: Expansion, pseudogenization and shrinkage, driven by reduction of phage pressure
