Our new paper is now out in Evolution! 🐟 We estimated the strength of directional selection on armor plates in threespine stickleback in Lake Washington, while accounting for migration and genetic drift. My first stickleback paper! doi.org/10.1093/evol...

New review out! With students in my lab, we explore how population size shapes speciation—from drift in small populations to selection in large ones. Do small or large populations speciate faster? The answer is more nuanced than you might think. esj-journals.onlinelibrary.wiley.com/doi/full/10....

Question for speciation researchers! I'm looking for "the most classic mathematical models of speciation" to introduce in my class. What comes to mind when you hear this phrase? Would love to hear what you consider the classical models in the field. I'll start first:

🚨 The New Age of global bird phylogenies continues! Hot on the heels of the fantastic updated tree created by @eliotmiller.bsky.social and others, we use a different approach to generate a near-comprehensive timetree of >9000 bird species. 1/3 www.cell.com/current-biol... 🧪🌐🪶

Exciting news! Our lab student Hidaka Kubo's (@hidakakubo.bsky.social ) first research paper has been published in the Journal of Theoretical Biology! www.sciencedirect.com/science/arti...

I made a starter pack of speciation researchers. Please let me know if you or someone you know would like to be added. I am particularly sad that so far there are not many speciation researchers from the Global South represented. go.bsky.app/J7qDY56
