A colorful legacy of hybridization in wood-warblers includes frequent sharing of carotenoid genes among species and genera Introgression between species can shape evolutionary trajectories in important ways. This study of the entire family of the colorful wood-warblers (Parulidae) uses whole-genome sequencing to reveal fr...

New paper out. If you like colorful birds, hybridization, and phylogenetics, read on! 🧵https://doi.org/10.1371/journal.pbio.3003501

I’m recruiting a PhD and MSC student for fall 2026 working on the movement ecology and conservation of Mexican spotted owls in SW forests and rocky canyonlands. Exciting partnership with Los Alamos National Laboratory. Great vibrant lab group, high impact research! 🦉

Oops… yes. I’m still getting them online for a journal submission. Will post here once done.

I have a new preprint demonstrating a genome-architecture-aware approach to inferring species trees and introgression landscapes from a small number of genomes. If you are interested in phylogenomics, birds, or hybridization, this is for you! www.biorxiv.org/content/10.1...

A figure showing the "core" and "periphery" of lowland forest in South America, a figure showing the genetic structure of our population genetic simulations, and a figure of three alternate divergence histories simulated.

Look forward to more about Solomon Island phylogeography in the future, but in the mean time, @lukemusher.bsky.social and I have a pre-print that highlights how a similar phenomenon can occur on continents (with bias in both topology and branch lengths): doi.org/10.1101/2025...

Figure with a photo of a member of then Solomons Monarch complex, a map of the Solomon Islands (divided into four island groups, Makira being the most isolated), and a principal component analysis highlighting the distinct between-island-group structure, with moderate structure within the New Georgia Group and weaker structure within the Bukida group (highlighted in an inset).

Just out in Systematic Biology, we explore the role of gene flow in island phylogeography of the Solomons Black-and-white Monarch complex. doi.org/10.1093/sysb...

Up first, strong genetic structure between islands groups and weak (but present!) structure between Pleistocene-connected islands (🧵)

We have a new preprint in the whole-genome phylogenomics of tinamous! We compare gene tree estimation error for protein-coding and ultraconserved elements and find these two data types behave quite differently. Also a new species! www.biorxiv.org/content/10.1...

Women remain underrepresented in academia www.science.org/doi/10.1126/...

Toxic workplaces are main reason women leave academic jobs www.nature.com/articles/d41...

Women faculty feel pushed from academia by poor workplace climate

Women more likely to leave academia due to work place climate than due to work family conflict.

Hermit crab (Pagurus prideaux) on the substrate looking up at you. Instead of a shell it is covered in an orange anemone (Calliactis palliata) with pink spots. Coming off that are neon pink silly strings, which are the anemone's tentacles! Photo by Darryl Meyer https://www.flickr.com/photos/27988477@N02/3992801991/in/photostream/

Hermit crab (Sympagurus dofleini) in the deep sea. It is facing to the side, with a purple striped sea anemone (Stylobates) covering its posterior, with the anemone's tentacles facing down. https://www.ncei.noaa.gov/waf/okeanos-animal-guide/Paguroidea015.html

4 different views of the carcinoecium produced by the anemone Stylobates aeneus, which look exactly like a snail shell. But they are not. Image by Chong Chen https://www.facebook.com/photo.php?fbid=10207492582127068&set=a.10200283324540134&type=3

Did you think hermit crabs always live in snail shells? 🧪🦀

Some deep sea hermit species live symbiotically with anemones that DISSOLVE the shell and SECRETE a new one ("carcinoecium") made of chitin! The carcinoecium has evolved at least 3 times! Photo credits in alt text. @megdaly.bsky.social

Hi folks! I’m an evolutionary biologist who studies speciation, genomics, and biogeography of birds and their ectoparasites. I’m currently a postdoc at the Academy of Natural Sciences of Drexel University.

I am!

With @thamnobravo.bsky.social and @rafamarcondes.bsky.social along with Greg Thom, Glaucia Del-Rio, and Robb Brummfield.
