Raymond Castillo

As you are making your schedule for the last day of #Evol2025 don’t forget to add Nicolás Castillo’s talk about Puya character displacement. Puya are the most amazing plant in the Páramo ecosystem and their macroevolution is incredible.

Last but not least, I will be sharing some work on a model I have been developing for chromosome evolution today! Be there or be square! I'll be presenting at 4:45 in Phylogenetic Theory! #Evol2025

Also, if you missed their poster last night, Sarah Swiston, will be presenting their work on elipse modeling for biogeographic range evolution! (EMPIRE)

Alright #Evol2025 folks, we got a ton of talks today!
Gabriel Garcia, a visiting PhD student from Brazil, will be sharing his work on ecological traits driving diversification in bats!

Today another postdoc in the Landis lab, @albertchristian.bsky.social, will be giving a talk during the machine learnering and new inference algorithm section at 3:15! If you are particularly partial to island biogeography you definitely dont wanna miss this one! #Evol2025

Be sure to check out Anna Nagel's talk today in Molecular evolution II! Really cool work on estimating mutation ages and population origins in structured populations! #Evol2025

Had a fantastic time at the mole 2025 workshop in Woods Hole! I am so grateful to meet such amazing scientists! Although times are difficult and uncertain now, engaging with professors and students who are still working so hard to teach and learn despite recent hardships is truly uplifting.

Updates on NSF Priorities

This is bad.

Read the updates.

Totally forgot to update: I PASSED!!!!!!
A small win after a lot of despairing the past few months with the political climate :')

Qualifying exam in a couple hours! Once it's over with I'll have to figure out a different way to distract myself from the existential dread that is US politics

SHARE WIDELY.
KNOW YOUR RIGHTS.

With mass deportations starting today across the country, it is vitally important - for both citizens and non-citizens - to know your rights.

You have the right to remain silent. Assert it. You have the right to a lawyer. Ask for one.

list comprehensions may never make 100% sense to me but at least the work 💀

Earlier this year my advisor @landismj.bsky.social and I published this cool work at BMB; looking at applying diffusion in macroevolutionary context for state-dependent diversification models to learn about evolutionary patterns that these models produce. #evobio

Here's a starter pack for early career researchers in evolutionary biology. I prioritized the most-junior folks, and this list quickly filled up with undergrads, grad students, and postdocs. Might do another list later, but I'm tired. Have fun everyone! 🐒 #evobio

time for end of semester despair yippee!

One of my peers and I are thinking of teaching a statistics nano-course for people in ecology and evolution, what are some statistical tests that you feel are important to your research?

also I am a queer latino whose grandparents immigrated from mexico so if that bothers you, i simply do not care! 😌

Hi to all new mutuals and fellow scientists fleeing twitter! Figure I should have a post about who I am! I am a phd student at WashU in the landis lab, developing phylogenetic methods! I am primarily interested in modeling chromosome evolution using SSE models!

A flyer for the next Polyploidy Webinar on November 6, 2024, at 11AM Pacific Time. It includes photos of the two presenters and their presentation titles. Sylvia Kinosian from the University of Arizona will speak on "Genomics is modifying our concepts of evolution in homosporous pteridophytes" and Tamsen Dunn from San Diego State University will present "Deciphering the Polyploid Ks Histogram with Forward Time Simulations."

Join us on Wednesday, November 6, at 11 AM PST for the the next #PolyploidyWebinar! Sylvia Kinosian and Tamsen Dunn will present. The zoom link will be emailed out before the talks - sign up here if you have not signed up before! www.barkerlab.net/polyweb

Join us tomorrow for the first #PolyploidyWebinar of the 2024-2025 series!

If anyone has read Inferring Phylogenies by Felsentein let me know! Id love to chat about particular chapters with someone as i read.

Alright gonna try reading Felsenstein for the first time... wish me luck🫡
