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.

Do mutations that drive evolution improve many traits or few? Does this change over the course of evolution? Excited to share our work in PLOS Biology exploring these questions in the first 2 adaptive steps w/ Yuping Li, @gsherloc.bsky.social, @petrovadmitri.bsky.social 🧵 doi.org/10.1371/jour...

Excited to share a new preprint with @jnovembre.bsky.social ! We use a combination of population genetic theory, simulation, and data analysis to ask: how does study design in genetic studies (including biobanks) impact the discovery of rare, deleterious variants?

The typeset version of our article, "Reconstruction of the human amylase locus reveals ancient duplications seeding modern-day variation", is now online. This thread will provide an overview of how gene duplications have shaped modern variation in the amylase locus. www.science.org/doi/10.1126/...

We usually think of genetic drift as the predominant stochastic force in evolving populations. But working with some model microbial populations, we found a distinct source of demographic stochasticity that scales (and behaves) differently than drift Learn more in our new paper 👉 rdcu.be/d07Np
