I’m at #SMBE2026 this week. My lab is looking to hire a postdoc to study the genetic and developmental mechanisms underlying the evolution of organs and cell types. Please reach out if you’re interested!

Thank you @genetics-gsa.bsky.social for an awesome #PEQG26 meeting! The Kreiner lab had a stellar time sharing our work and catching up with folks on the latest. Till next time!

We are excited to share our pan-pangenome paper! This is a long time coming work of my postdoc with the incredible @psudmant.bsky.social, and a stellar group of people! I hope you enjoy reading it! And I am excited to talk more more about it this week at #PEQG26!! www.biorxiv.org/content/10.6...

Abstract deadline for Midwest Pop Gen 2026 extended to June 12th! Aug 21-22 at UChicago — free, trainee-oriented meeting with talks, posters + Friday BBQ at Promontory Point. Chicago in August doesn't get better than this... jkreinz.github.io/mwpg2026

I'm looking to hire a postdoc. Please share if you can!

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:

We are looking for a postdoc to help with a project on eelgrass genomics, in collaboration with the O'Connor and Rieseberg labs at UBC - see ad here tinyurl.com/2yd487p4! Come and join us in beautiful Vancouver 🌊🌾🏔️

1/11 🔥 New preprint alert 🔥 We wanted to know what plants in the wild really care about. So we asked them 🎤. Here is what we learned: “Biotic-response networks are an important organizer of the transcriptome in wild Arabidopsis thaliana populations” www.biorxiv.org/content/10.6...

Building a pop genomics lab around selective sweeps in the DGRP dataset, but can't track down a VCF online. Federal funding casualty? Anyone know where to find a working link?

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

Huge congrats to @reginafairbanks.bsky.social who was just awarded a Chicago Fellows postdoctoral position to go work with @jmkreiner.bsky.social on the population genetics of adaptation in Amaranthus!

We are delighted to announce that the winner of the 2025 New Phytologist #TansleyMedal is @camilledelavaux.bsky.social! Read the #Editorial by Slater & Dolan 👇 📖 nph.onlinelibrary.wiley.com/doi/10.1111/... #LatestIssue #PlantScience @niooknaw.bsky.social 🧵1/2

Applications are currently being accepted for UBC's ✨️ Biodiversity Postdoctoral Fellowship ✨️ (two positions!!), due Jan. 15 Please share far and wide 🚀 (See thread)

One of the most exciting works of my career, years in the making. We used high-throughput precision genome editing to test the fitness effects of thousands of natural variants. Our findings challenge the long-held assumption that common variants are inconsequential. www.biorxiv.org/content/10.1...

Great new postdoc fellowship for foundational plant research. If you’re into genetics and genomics of plant reproductive evolution or adaptive convergence (incl in the cool and charismatic nightshades!) I’d be happy to talk about possible projects! www.simonsfoundation.org/grant/simons...

Human-mediated land-use and climate change occur simultaneously, but how do they interact to shape adaptive dynamics? Super excited to share the first paper from the Kreiner lab, led by postdoc extraordinaire @rpineau.bsky.social

Join us tomorrow (30 Sept) at 14:00 BST to hear from 2024 #TansleyMedal winner Matthew Naish! Matthew will be talking about unravelling plant centromeres in the telomere-to-telomere era. Registration is free: www.newphytologist.org/events/2025-... #PlantScience

Asters and goldenrods, Maple Grove Forest Preserve, yesterday morning. Fight for democracy, science, human decency, and the natural world, and continue celebrating what you are fighting for.

New — with @joannarifkin.bsky.social, @jotlovell.bsky.social, @spicybotrytis.bsky.social, and many more — we created seven new high-quality genomes and explored pangenomic variation in the emerging oilseed crop pennycress (Thlaspi arvense). 1/

This was a HUGE effort, taking years of diligent work. Hongfei was a true leader, and I'm really proud of this cool piece. We'd love any feedback y'all might have. www.biorxiv.org/content/10.1...

Fun to synthesize some exciting future directions for spatiotemporal genomics in this Tansley perspective. Check er out!

I'll start reviewing applications in a little over 3 weeks for this PhD position. You could be doing fieldwork here! (or focus only on dry lab work if that floats your boat)

Would be excited to chat with folks looking for a postdoc in AI to develop models for genomic prediction... A great opportunity for funding coming up soon is the Schmidt AI in Science fellowship, due October 13th! apply.interfolio.com/173322

Very excited to see this work in press! I think there is a reason to believe that this is a common means of stabilizing large-effect polymorphisms in general and might be an important reason for why diploidy is so common. news.stanford.edu/stories/2025...

How do populations maintain an evolutionary memory? I am happy to share that our work with Dmitri Petrov @petrovadmitri.bsky.social, Paul Schmidt, and colleagues on dominance reversal and stabilization of insecticide resistance in changing environments over time is now published at Nature EE.

We’ve just published a paper on Senecio showing that ecological speciation and mutation-order speciation can act together rather than as an either/or. Congratulations, Maddie James and MC Melo!

Our new Nature Plants paper is out (and we’re on the cover 😁)!👉 bit.ly/4lS8sOB By combining scRNA-seq with conserved TF binding (multiDAP) we define gene regulatory networks for 65 cell types across 4 tissues in a wide range of flowering plants!

"...science loses meaning if it comes at the cost of human potential, and mentorship is, at its core, about nurturing that potential." Wise words from Brandon Gaut, whose essay is worth a read for mentors and mentees alike. We're so glad he is the recipient of our inaugural GSA Mentorship Award.

New paper out on the dangers of using patterns across spatial climate gradients to predict what will happen with changing climate. That includes species distribution modeling. Space-for-time substitution can be misleading in sign, not just the magnitude of effects. www.nature.com/articles/s41...
