Excited to share a study led by my postdoc Naseem Samo. If you evolve an "unusual" telomere DNA does your telomerase also coevolve to maintain interaction with that strange telomere? Answer we find is YES! www.biorxiv.org/content/10.6...

Rapid evolution and functional divergence of the monkeyflower Mimulus lewisii telomerase

Telomeres are nucleoprotein structures that protect chromosome ends and are maintained by the Telomerase Reverse Transcriptase (TERT) protein that uses a noncoding Telomerase RNA (TR) as a template. I...

Maintenance of phenotypic divergence in two sympatric monkeyflowers with weak reproductive isolation

Sympatric species often exhibit permeable reproductive barriers, yet many of them coexist as phenotypically distinct entities. One way to account for this apparent paradox is that selection on loci th...

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...

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:

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!

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...

Massively parallel interrogation of the fitness of natural variants in ancient signaling pathways reveals pervasive local adaptation

The nature of standing genetic variation remains a central debate in population genetics, with differing perspectives on whether common variants are almost always neutral as suggested by neutral and n...

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...

Classic recessive-or-dominant gene dynamics may not be so simple

New fruit fly research provides the first direct evidence of “dominance reversal,” revealing why pesticide resistance is so hard to eliminate in changing environments.

How is functional variation at large-effect loci maintained in natural populations? Thrilled to share our work showing how beneficial dominance reversal helps fruit flies maintain a resistance polymorphism as selection varies in their environment! A thread 🧵 1/n www.biorxiv.org/content/10.1...
