It took forever but my last paper as an academic is finally out. ironically this paper probably has the smallest audience, but I believe is my most impactful work. I think it provides some nice support for theories on polyploid origins, and has practical implications in crops and conservation

Delighted to see our work on the cover of Systematic Biology!! We introduce an approach for analyzing pairwise-defined traits (e.g. 'strength of RI', 'diet niche overlap') in a phylogenetically informed context (R package 'phylopairs' now on CRAN). Read it here: academic.oup.com/sysbio/artic...

Attention to people living in Illinois, Chicago: you have until Thursday to register a formal message to the state legislature that requiring age verification to install Linux is a horrible idea. This doesn't require writing anything, just filling out a form. Click through this quoted post:

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...

Upcoming seminar in the @eseb.bsky.social Internal Conflicts and Organismal Adaptation Special Topics Network Really looking forward to Tuesday next week, March 17, when we have @mobilepurin.bsky.social and @manishamuna.bsky.social presenting. Join us! Zoom links etc in the post below.

Brent Pedersen, Mitchell Vollger and I have "posted" our preprint of the manuscript describing bedder, a complement to the functionality of bedtools. The "preprint server" we have chosen is google docs because it was rejected by biorxiv. docs.google.com/document/d/1...

In a new study, Sarah Marion &co use genetic mapping and whole genome sequencing in wild #Drosophila to reveal the genetic basis of naturally occurring lethal mutations and introduce a new model that could explain their frequencies in natural populations. 🧪 #genetics

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!!!!!!!) link: www.sciencedirect.com/science/arti...

Have you ever wondered how many archaic populations contributed DNA to modern humans? We know about Neanderthals and Denisovans, but the fossil and genetic evidence suggests a much more complex history! www.biorxiv.org/content/10.6...

The Goldberg lab at UCLA is hiring one or more postdocs. Flexible start date. We develop methods to study population genetics of humans, our primate relatives, and our pathogens. www.goldberglab.org/join

@pratikkatte.bsky.social and I just released Lorax 🌲, a tool for interactive exploration of biobank-scale ancestral recombination graphs (ARGs). If you’ve ever wanted to scroll across the ancestries of thousands of genomes… this is for you.

Our paper is out in @Science! The Atlantic silverside spans Earth's steepest latitudinal gradient in coastal sea-surface temperature. Despite high gene flow, populations show clinal genetic variation in multiple locally adapted traits. doi.org/10.1126/scie...

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

So excited to share this manuscript led by the inimitable Cara Brand, who discovered that Topoisomerase II evolution causes hybrid female lethality in Drosophila. Congrats to Cara, @nickbr0wn.bsky.social, Anirban, and @buszczaklab.bsky.social! 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.

New paper! From Sam Snodgrass and @genomeofforrest.bsky.social, w/ @druncie.bsky.social, @gcbias.bsky.social, and a collaboration with Andres Moreno and @santiagogmm.bsky.social. Can we quantify the impact of humans on maize dispersal? Plant yourself in a comfy chair and lend me your ear: 1/10

Check out this preprint. Tianlin Duan led this project during her postdoc with me and Mike Whitlock. It’s got a lot of stuff in it for those who are interested in the genomics of adaptation

New preprint! and my first single-author paper, so bear with me. www.biorxiv.org/content/10.6... Malaria population genetic studies have found some puzzling patterns: Ne estimates spanning orders of magnitude, genome-wide negative Tajima's D, and over a quarter of genes with πN/πS >1 1/n

We (with Fanny Pouyet and Brian Charlesworth) provide a theoretical perspective on rescaling forward simulations in population genetics, along with some guidelines: arxiv.org/abs/2601.05367

Congrats @jeffgroh.bsky.social et al. Some avocado trees open female-phase flowers in the morning & then male in afternoon. Others show complementary pattern (m->f), to synchronize pollination of two types. Jeff show this to be a >45Mya polymorphism at a transcription factor across 100s of species.

Do extra chromosome sets mask bad mutations? Simulations show tetraploids often carry higher genetic load than diploids, depending on dominance, demography, and drift—with important implications for fitness and conservation. academic.oup.com/evlett/artic...
