I'm excited to share that our latest paper is now out in PNAS! www.pnas.org/doi/10.1073/... It was a pleasure working with @landismj.bsky.social and Ammon Thompson on this project, developing a new phylogenetic model for infectious disease transmission with realistic host movement dynamics. #evobio

I’m recruiting a PhD student to join our lab in the fall of 2027. If you’re excited about phylogenetics, comp bio, paleobiology, stats theory, macroevolution, etc. please get in touch! Folks at #Evol2026, you can talk to @brpetrucci.bsky.social & @sigournie.bsky.social to learn more about our lab

Had a great post-SSB hackathon with the RevBayes crew! Got tons of work done on both RevBayes and RevGadgets! Special thanks to @trayc7.bsky.social @jembrown.bsky.social for organizing and hosting!

The wonderful Emily Graslie talking to the #SSB2026 crowd about the importance of natural history museums. She has an art background and became enamored with the University of Montana natural history collections and created the #brainscoop series.

I am still actively looking for postdoc positions — please lmk if you (or your friends and colleagues) need a hardworking postdoc with field, lab, and bioinformatic skills! I am broadly interested in evolution in the ocean, conservation and population genetics, and rapid evolution.

Overheard a conversation from an UG walking on campus. They said "I don't think I could have done my degree without AI". It's somewhat frightening the reliance some have on AI and I'm uncertain of its increased use at universities, but maybe i'm becoming the old man shaking his fist...

I am so happy to have successfully proposed my dissertation chapters! Despite how nervous I was, it went over so well and all of my committee members are so incredibly helpful!

As you are making your schedule for the last day of #Evol2025 don’t forget to add Nicolás Castillo’s talk about Puya character displacement. Puya are the most amazing plant in the Páramo ecosystem and their macroevolution is incredible.

Last but not least, I will be sharing some work on a model I have been developing for chromosome evolution today! Be there or be square! I'll be presenting at 4:45 in Phylogenetic Theory! #Evol2025

Had a fantastic time at the mole 2025 workshop in Woods Hole! I am so grateful to meet such amazing scientists! Although times are difficult and uncertain now, engaging with professors and students who are still working so hard to teach and learn despite recent hardships is truly uplifting.

Here's a starter pack for early career researchers in evolutionary biology. I prioritized the most-junior folks, and this list quickly filled up with undergrads, grad students, and postdocs. Might do another list later, but I'm tired. Have fun everyone! 🐒 #evobio go.bsky.app/MzND7nX
