Professionally playing with plasmids!
Postdoc-ing until someone here scouts me for a PI position ;)
Princeton EEB -> Harvard Medical School -> Soon ETH Zürich!

This is it!!! This is the work I never want to stop hearing about. Kepler’s creativity and curiosity really shine through in this paper. Give it a read and enjoy 😎
What is the best strategy to win any contest?
Eliminate your opponents of course.
Recently, my friend @fernpizza.bsky.social showed how plasmids compete intracellularly (check out his paper published in Science today!). With @baym.lol, we now know they can fight.

This has been an intense, crazy week. My plasmid competition paper is finally out and we have a new preprint on Bioarxiv! Plus I'm leaving the US after 10 years here. See you soon America! Hello Zurich!!!
Hot off the press! Our latest paper led by @fernpizza.bsky.social, understanding how plasmids evolve inside cells. These small, self-replicating DNA circles live inside bacteria and carry antibiotic resistance genes, but also compete with one another to replicate. 1/

Intracellular competition shapes plasmid population dynamics
From populations of multicellular organisms to selfish genetic elements, conflicts between levels of biological organization are central to evolution. Plasmids are extrachromosomal, self-replicating g...

When different kinds of mobile genetic elements get together, they become even more powerful catalysts for microbial evolution! In this work we discovered a mechanism by which Insertion Sequences drive their spread across Plasmids, which helps explain this evolutionary potential!

I'm so happy that I can finally share the results of my first postdoc paper with @baym.lol!!! Turns out plasmids are an amazing system to study multi-scale evolution and we can track within-cell and between-cell dynamics!
