Come work with us!

I'm excited to tell you about the most recent preprint in my lab, demonstrating that a conserved spindle matrix protein, NPP-21/TPR, is required for the stronger checkpoint in germline cells during embryogenesis in C. elegans

So good!

It's looking increasingly likely that I'll be hiring a 3-year computational pop-gen postdoc/PhD-level scientific programmer to start this Fall (2026). If you or someone you know is defending soon, and looking for a position, please DM/write to me! Thanks!

Allelic Variation at tRNA Genes in Three Nematode Species Indicates Mutation Load Despite Strong Purifying Selection Abstract. Cytosolic transfer RNAs (tRNAs), which are encoded as hundreds of genes in nuclear genomes, experience exceptionally high mutation rates and have

Now published @genomebiolevol.bsky.social: our paper showing that the genes for critical, ancient components of protein synthesis machinery - tRNAs - are bombarded with mutations, leading to remarkable allelic diversity that likely has functional consequences!

Pervasive Fitness Trade‐Offs Revealed by Rapid Adaptation to Shifting Population Densities in Large Experimental Populations of Drosophila melanogaster Trade-offs are an inherent feature of organismal biology and fundamental to the evolution of natural populations. Using experimental evolution in large, genetically diverse populations of Drosophila ...

Really excited to see this work out now in Ecology Letters!
May be particularly interesting to those thinking about life-history trade-offs and eco-evolutionary feedbacks, and how those may interact to maintain variation within natural populations.

I defended my PhD 10 years ago today. That was the least remarkable thing that happened that day. Sharing something I wrote about it last year. Since then "the horrors persist but so do we." And with dignity.

Introgression and parental conflict shape repeated occurrences of postzygotic isolation in Mimulus Postzygotic reproductive isolation is often thought to accumulate as a byproduct of neutral divergence. Yet it frequently evolves rapidly, in line wit…

I am SO THRILLED to share our first fully-lab lab paper!!!!!! Led by @hybridzones.bsky.social & @hagarsoliman.bsky.social, w/ a major assist from @pfschwarz.bsky.social!!!!!!!!!!!!! Read more below, if you're curious (you should be- it's AWESOME!!!!!!!)

Join us at the Evolutionary Biology Centre at Uppsala University. We’re searching for an Assistant Professor in Biology. www.uu.se/en/about-uu/...

Homepage - 2026 Population, Evolutionary, and Quantitative Genetics Conference Visit our website to learn more.

PEQG! My favorite conference ever*. Single session, fantastic talks, great discussions. Only once every 2 years. And in the best conference location too! Abstract deadline coming up Feb 5!

*Disclosure: I am required to say it's the best conference because it is and I told my mom I wouldn't lie.

The Abreu lab at NYU is hiring another postdoc! We study microbial ecology and evolution, using yeast/bacteria microcosms, DNA barcoding for evolutionary lineage tracking, and simple mathematical modeling. Apply here: apply.interfolio.com/179949

What happens when scientists studying population, evolutionary, and quantitative genetics all get together in one room? You get #PEQG26! Hear why PEQG 2026 stands apart directly from conference organizers: buff.ly/O0jiIBE
