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.

Check out our paper in Evolution Letters! We used D. melanogaster pigmentation as a focal trait to explore parallelism in phenotypic and genomic responses to environmental change - read more at the link below 👇

I am seeking a postdoc for my group at UCLA. We work at the intersection of population genetics x microbiome (garud.eeb.ucla.edu). If interested, please message me!

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...

Thrilled to see this work, led by @lisacouper.bsky.social now out! We quantified variation in thermal tolerance in the mosquito, Aedes sierrensis, to quantify how adaptation may alter disease vector distributions under warming. 🧵 www.pnas.org/doi/10.1073/...

Happy that this paper - www.biorxiv.org/content/10.1... - was accepted at Mol Ecol Res and excited about the promise of this technology to measure pop sizes for such elusive species as snow leopards + learn about at least 1st-degree relationships + beyond? Congrats to Katie Solari and other authors!

This collaboration was such a pleasure. Our new paper on cascades of HT after introduction of two TEs to human commensals www.nature.com/articles/s41...

I enjoyed participating in the symposium on genetic time series to understand microevo & eco dynamics @ ASN25 organized x Brian Reid & featuring @meaghansaurus.bsky.social @markcbitter.bsky.social @renedelight.bsky.social @isaacovercast.bsky.social ! Can you believe this incredible impromptu art?!

Registration is now open for the Gordon Research Seminar (GRS) on Ecological and Evolutionary Genomics in Tuscany, co-chaired by me and @jcbnunez.bsky.social! www.grc.org/ecological-a...

This meeting is a unique opportunity for early-career researchers to present their work and network. The GRS precedes the GRC, which features an incredible line-up organized by @chicascientifica.bsky.social and @samyeaman.bsky.social For more information about the GRC: www.grc.org/ecological-a...

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
