Avocados come in 2 varieties - A-types start each day female and switch to male midday. B-types do the reverse. In work just published from the last chapter of my PhD, we show this system evolved 40+million yrs ago and is regulated by alleles of 1 transcription factor www.pnas.org/doi/10.1073/...

Balanced polymorphism in a floral transcription factor underlies the ancient rhythm of daily sex alternation in avocado | PNAS

In avocado and certain wild relatives in Lauraceae, a highly synchronized daily rhythm of floral sex timing promotes cross-pollination between two ...

🚨 We're hiring computational evolutionary biologists! 🚨 Boosting this - industry evolutionary biology jobs don't come along often, so if you're excited to apply your computational evolutionary biology skills to cutting-edge problems, let's talk! 🧪🧬💻

Our team at @arcadiascience.com is hiring! We're looking to hire a computational evolutionary biologist interested in asking how and why protein sequences/structures/functions differ across the tree of life 🧬 jobs.lever.co/arcadiascien... Please share widely!

Do you like Arabidopsis thaliana? Do you like linked selection? Are you at #PEQG26? Well you're in luck! Come by my poster 244W tonight, June 10th, and hear about my attempts to estimate the extent of linked selection in Arabidopsis thaliana evolution experiments.

So no publication fees, no conferences, no international collab, and we can terminate or reject your grant anytime for any reason. This might have some impact on how science works, folks. And maybe just maybe not a positive one.

What a nice day: Great people that I know getting tenure, getting into the national academy, or wrapping up their last PhD Committee meeting as they think about future postdoc positions. Science is awesome and the people that make it happen are awesome. Keep pushing forward everyone.

Please circulate: I will have a postdoc opening soon, ideally with a start date sometime this summer or fall. If you're interested in empirical population genetics, computational methods development, and/or evolutionary modeling via simulation, don't hesitate to reach out. For more info on the lab:

Excited to share our new preprint! 🍇🧬 We analyzed 639 genomes across 48 grape species to understand how hybridization drives adaptation. • ~14% of average Vitis genome is introgressed • Most parallel adaptations are shared via gene flow • Two "hybrid species" are actually hybrid swarms

I am seeking a postdoc to join my group at UCLA -- ideally the candidate would have some experience in either population genetics or microbes/microbiome (computational background needed). We have a range of projects and are happy to tailer to your interests. Please dm/email me if interested.
