Hi everyone, I just started a bluesky account to share my work and keep up with the work of others :) ! I am very pleased to share this review on the evolutionary causes behind the existence of meiotic recombination hotspots: doi.org/10.1371/jour... I hope it will be useful to some of you!

doi.orgWhy recombination hotspots?Meiotic recombination is the process by which DNA is exchanged between parental chromosomes during the production of gametes in eukaryotes. This phenomenon has important implications for fertility, ge...

Amazing work by Enzo Marsot, our PhD student, clarifying that: - Ghost LTT - Ghost speciation times - Birth-death-sampling parameters (identifiability recovery) - Complete species tree topology (including ghosts!) Can theoretically be recovered from gene trees (if HGTs): doi.org/10.64898/202...

Accompanying the publication of my second PhD paper today, I wrote a little bit about the behind the scenes. How did this project come about? Inspiration can come from many unexpected places. I’m so grateful that Scott and Matt gave me the opportunity to follow my passion and curiosity!

I wrote about a reason not to use generative AI in your writing that I haven't seen anyone talking about. Once I realized this, banning GenAI in our lab's writing became a no-brainer. Feel free to share, I think this is probably useful especially for trainees: www.carlsonlab.bio/thoughts/the...

carlsonlab.bioThe only reason you’ll ever need not to write with AI — The Carlson LabOver the last year, our lab has been developing a policy on AI use. To do this, we did three main things: We read a lot of academic publications and tech news. We set up an #ai channel on our la...

Last year we took a small amber with a fossil bee to the Oxford synchrotron. Little did we know that it would become a tiny window into the ecology of bees and their mites in the subtropical forests 40 million years ago. @charliezoology.bsky.social @hfspo.bsky.social www.cell.com/iscience/ful...

🏔️🐟🧬 Excited to share my first PhD publication! We investigated how phenotypic plasticity, rapid selection, and genetic drift contribute to rapid phenotypic divergence in Arctic charr populations isolated for just over a century. Thanks to all my co-authors, collaborators, and reviewers! 😊

Allopatric isolation under contrasting environments can drive rapid phenotypic divergence, even over contemporary timescales. Rapid changes in mo

Meiotic drive has long been considered as a genetic curiosity. Genomic "footprints" suggest otherwise. Check out our new review doi.org/10.1093/molb..., a cross-taxa synthesis arguing that recurrent drive is a pervasive and underappreciated force in genome evolution.

Very happy to have contributed to the study of the genomic differentiation of the British swallowtail butterfly (Papilio machaon britannicus). Despite the regular immigration of P. machaon from the nearby mainland, the British swallowtail butterfly remains genetically distinct. 1/..
