We are pleased to recognize two Honorable Mentions for the SSE Presidents’ Award this year: Skylar Berardi and Miles Roberts for their papers in Evolution Letters! shorturl.at/CpcoY @evolletters.bsky.social

I am excited to share our latest paper, Uniform bacterial genetic diversity along the gut, now out in Nature Communications! www.nature.com/articles/s41.... (1/n)

Really excited that this major work from my PhD is finally published in @plosbiology.org ! In it, we were trying to tackle a fundamental question in evolution - how do genetic mutations map onto evolutionary fitness? (1/n) journals.plos.org/plosbiology/...

Have you ever wondered 🤔... Does phenotypic variance respond to environmental perturbation? Does it have a genetic basis? Are mean and variance regulating loci exposed to different selection pressures? These and more questions are explored in our new preprint 🔥 www.biorxiv.org/content/10.6...

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.

Scientists across the career spectrum are burnt out, & people are leaving STEM in startling numbers, particularly those from under-represented groups. A lab handbook can foster a more positive research culture. By @scattercushion.bsky.social @nature.com 🧪 www.nature.com/articles/d41...

Very excited to be going to the Annual Drosophila Research Conference @genetics-gsa.bsky.social in Chicago this March. I think #Dros26 is the hashtag. There is still time for you to register! The fly community is so welcoming and supportive—if you are new to flies please consider going.

Excellent piece by Matz @heatshok.bsky.social and colleagues discussing the dire status of Caribbean reefs, and potential plans and policies that can be implemented if these reefs are to have any chance. Check it out in PNAS!

Registration is open for the inaugural GRC conference in the Function of Evolving Systems. Aug 9-14, 2026, Waterville Valley. Truly stellar speaker lineup. Student/postdoc fellowships are available! Please come join us! www.grc.org/function-of-... @joybergelson.bsky.social

How does the strength of genetic drift evolve over long times? New preprint out 👇 www.biorxiv.org/content/10.6...

Excited that SpaceBar is now out in Nature Methods!🥳 We combined clone tracing with spatial transcriptomics to untangle what drives gene expression in tumors: a cell's identity or its neighborhood? Most genes were driven by location, but some showed strong clonal patterns. rdcu.be/eVhpc

Working on this paper fundamentally changed how I thought about bacterial evolution, and I couldn't ask for a better to Hannukah present than to see it out, at last!

If you are interested in this work and are looking for a postdoc position, please get in touch -- we are actively looking for someone to join our group at UCLA!

Grateful to share our paper on gene-specific selective sweeps in human gut microbiomes, now out in Nature! It has been a joy to work with @rwolff.bsky.social, whose insights and hard work made this possible. www.nature.com/articles/s41...

So excited to share this work led by @alexrob.bsky.social with Ben Kerr! We investigated a poliovirus capsid inhibitor that exploits a breakdown in the genotype-phenotype map to prevent drug resistance evolution. Or does it? See Alex's thread, but a few extras: #socialviruses #evosky #virosky 🧪

Genuinely one of the most important and interesting papers I have been a part of! Relevant to fundamental questions regarding the predictability of adaptation, as well as the applications of genomic data. Congrats to @j-smiley-rhodes.bsky.social and all co-authors for such a masterpiece!

Super excited that the bulk of my PhD work is now preprinted! Here we used whole-community competition, or coalescence, experiments to quantify selection acting on genetically diverged strains within larger communities. (1/n) www.biorxiv.org/content/10.1...

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...

One week to apply for our fully funded PhD position in Norway! This is a really exciting project in collab. with University of Helsinki and Benchmark Genetics. Samples are ready - you do (read: learn) everything - functional genomics, bioinformatics, genotype-phenotype associations 🤩 Please RT!

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

New preprint led by undergrad Owen Moosman! We uncover extensive haplotype diversity in antifreeze protein gene copy number in polar Zoarcoidei fishes, and report new tools to evaluate assembly uncertainty and switch error in phased genomes www.biorxiv.org/content/10.1...

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.
