I’m looking to hire an NIH funded postdoc to join our lab here at Davis (please RT). Ongoing areas of interest include: 1) polygenic signals of selection from time series, ARGs, GWAS, etc 2) The interpretation of GWAS, polygenic scores, & sources of confounding

Been working on my NSF PRFB proposal for what seems like weeks now. Thankful for the examples provided in @jrossibarra.bsky.social 's github page (github.com/RILAB/statem...). The current call is AI in biology, and fortunately thats a lot of what I do, so I'm giving it a shot!

We're hiring an ecologist at UC Berkeley! The Dept. of Integrative Biology is hiring a tenure-track Assistant Professor in Ecology. Plants/algae, invertebrates, microbes, or marine systems a priority. Come join us!! Apply by Oct 5, 2026. aprecruit.berkeley.edu/JPF05489 PS: Please share!

New paper out in PNAS! 🍇🧬 Vitis phylogenomics is a tangled vine. Highlights: • ~14% of the average grape genome comes from introgression • Two classic “hybrid species” are better described as hybrid swarms • Repeated adaptation is fueled by introgression and standing genetic variation

Find myself and the rest of the Specht lab at Botany 2026!! #PlantPeopleFTW #Botany2026 @botanyballer.bsky.social @brythebotanist.bsky.social @arayabelle.bsky.social @jlandisbotany.bsky.social @spechtlab.bsky.social

uchicago.wd5.myworkdayjobs.com/External/job... The Kreiner and Carley Lab groups are hiring a shared Research Analyst to help lead wet lab protocol development and management. We're a fun group and would love to hear from you :) Get in touch with questions!

Just posted: a group paper describing major updates to my software pixy, for population genetic summary statistics. www.biorxiv.org/content/10.6... New since 2021: arbitrary ploidy, multiallelic sites, missingness-aware Watterson's θ and Tajima's D, Hudson's FST, multicore execution!

Hey Botany! Come see my talk investigating whether polyploids have different patterns of flower evolution than diploids on Weds at 8:15am in San Xavier. Over 100 undergrads participated in this research! :) #PUIFTW #Botany2026 #PlantPeopleFTW

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/...

Did you know that the flowers of avocado trees change sex every day? Scientists have noticed this nearly 100 years ago but only now do we how it works. Life is amazing.

Folks! @gcbias.bsky.social and I have two slots left in our popgen workshop. Aug 10-21, 9-11am (Pacific) via zoom. We’re raising money for research grants for grad students. $500 a seat. Spots available to first folks to respond. DM me if interested.

Job opening: I'm looking for a lab tech primarily supporting ongoing projects and running computational analyses for the lab. Apply here and reach out with questions! utah.peopleadmin.com/postings/205...

PhD Position at Uppsala University. Sophie Karrenberg’s Lab. the project is about sex chromosome evolution in plants. Come join us! Deadline 22 July. www.uu.se/en/about-uu/...

🚨 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! 🧪🧬💻

Nice writeup of the impacts of great instructor (yes, this is a Brandon Gaut stan account) www.bio.uci.edu/students-bri...

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.

Excited to be at #PEQG26! I have a poster tonight on measuring selection on intraspecies variation in large microbial communities (415W), would love to hear what folks think!

How do plants locally adapt to challenging habitats despite ongoing gene flow? Come find me tomorrow at poster 236W to chat about life history divergence on small spatial scales in the yellow monkeyflower! #PEQG26

My poster number is 375! Ohh, looking forward to checking that out!!

Having a great first experience at #PEQG26 ! So many cool projects and friendly people. Come visit me at my poster tomorrow to talk about TEs and SVs!

I am recruiting a #postdoc to work on assembling and analyzing #genomes of the amazing Furnariidae. Let’s unlock the secret behind their #evolution. The official application portal will be available soon at www.uno.edu/careers. Feel free to contact me for details at sclaramu@uno.edu

The list of Ecology/Evolution/Marine Bio Labs recruiting grad students for Fall 2027 is live! PIs enter your position info here: forms.gle/MAGd4ohyPeoY... students (and PIs not recruiting) share the composite list: docs.google.com/spreadsheets... Please share widely! 🧪

postdoc alert 🚨! NIH-funded postdoc in my lab to work on Ancestral Recombination Graphs in space. Please spread the word widely in your networks, and please reach out if you're interested! (2-3yr position, start date flexible, pay/benefits good!). details here: careers.umich.edu/job_detail/2...

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.

Update! The posting for the postdoc opening in my lab is up! Apply here: unc.peopleadmin.com/postings/319...

Friends don't let friends copy pasta AI-generated citations of imaginary papers

We are hiring! We’re excited to recruit a postdoc to our lab at UC Davis to work on plant immune engineering and single-cell analyses of plant pathogen interactions. Apply by June 1. Please repost. www.coakerlab.org/postdoctoral...

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.

Congrats to @jrossibarra.bsky.social on being elected to NAS!!! 🌽💻🧬🎉

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:

I'm hiring a postdoc (start date flexible) and a PhD student (for Fall 2027) to work in any area of computational phylogenetics! More info here: mhibbins.github.io I will be attending both PEQG and Evolution in June, so please reach out if you want to chat at these meetings!

Thank you @adrigov.bsky.social for the nice summary in Plantae.org of our paper!

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.

Interested in working to apply ARGs to real data in messy plant genomes? (Yeah it sounds hard). DM or email!

Friends, please help spread the word about our microbiology REU program at Montana State University. www.montana.edu/mbi/reu/ Each student receives a stipend ($7000 for 10 wks). Travel compensation, room, and board are also provided. Details in the attached pic--Feb 14 deadline 🧫🧪🦠#microsky

Congrats @jeffgroh.bsky.social et al. Some avocado trees open female-phase flowers in the morning & then male in afternoon. Others show complementary pattern (m->f), to synchronize pollination of two types. Jeff show this to be a >45Mya polymorphism at a transcription factor across 100s of species.

Check out our new paper! :)

Our plant-focused REU program, led by Prof Nagel, is open for applications, please forward to undergrads and reskeet etap.nsf.gov/award/7573/o... 🌱 🧪
