I am super excited to meet up with a preschool class for @skypeascientist.bsky.social today!! Not sure what that probabilities are (I am guessing low), but I just found out that out of the thousands of possible pairings, I get to visit my sister's classroom thousands of miles away!!

Surprised to learn scientists can't agree on a definition of sex? Don't be! To be honest, we can't even agree on a definition of species. Many so-called natural categories are hard to define once we look at the evidence. Biology is too complex for simple definitions, which is a feature, not a bug.

"The fact that there is no current consensus of biological sex is not antithetical to science... However, the field urgently needs an ethical and reproducible approach for discussing sex" There is No Consensus on Biological Sex

new paper from my phd is now out as a pre-print @biorxiv-evobio.bsky.social!! we leverage a novel gt-seq panel to investigate a marine ecology “black box” — population connectivity! read here: www.biorxiv.org/content/10.6...

📣 A perspective with @allydefduf.bsky.social @madeline-eppley.bsky.social and others out in @ecol-evol.bsky.social 📣 Drawing from queer lived experiences, we offer new perspectives to confront existing biases in #ecology and #evolution. onlinelibrary.wiley.com/doi/abs/10.1...

hit a little scientific milestone today: 50 citations!!!!! sometimes I am still in shock that I am living my childhood dream and get to be a ~scientist~

On this Trans Day of Visibility, please enjoy & learn something from this fascinating & clarifying read from @madeline-eppley.bsky.social, @andylee.bsky.social, Robert Dellinger & @allydefduf.bsky.social Read👉 onlinelibrary.wiley.com/doi/full/10.... (🙏 for this excellent work & actionable recs!)

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.

Always enjoy reading a dissertation - I try to give it time and respect. We are all so rushed, but somebody worked their f**king ass off for this, and I'm so pleased for the person defending their work this week. So, diving in ahead of time.

It finally happened to me: I read this whole paper and was like "hell yeah this is great" and then saw I was thanked in the Acknowledgements, which I had forgotten about lollll Faculty-brain is real

What is the relationship between science and society? How does culture impact the production and dissemination of knowledge? In this new paper, Eppley et al interrogate how systems of oppression bias our research, and how Queer perspectives can address these. onlinelibrary.wiley.com/doi/10.1002/...

Fantastic paper! I was coincidentally thinking earlier today about how we sex baby juncos (genetic) and juveniles (wing size) and what the error rates are. I thought "at least we can tell for reproductive adults", but this paper reminded me that it's possible we're getting some of those wrong too.

ICYMI: in our new paper, we contend there is "no current consensus on a definition of sex that is free of assumptions and limitations... and most importantly,...no biological definition of sex should be used to dictate human rights" #evolsky #LGBTQSTEM #ecology #evolution #biologicalsex

I am still actively looking for postdoc positions — please lmk if you (or your friends and colleagues) need a hardworking postdoc with field, lab, and bioinformatic skills! I am broadly interested in evolution in the ocean, conservation and population genetics, and rapid evolution.

New paper out in ecology letters! with @andylee.bsky.social @allydefduf.bsky.social We synthesized the active debate on how scientists define sex, including limitations and assumptions. We believe this discussion will lead to more accurate science. onlinelibrary.wiley.com/doi/10.1111/...

Very proud of this perspective that came out of some really interesting and difficult conversations with friends and colleagues! TLDR: how do scientists define sex? why does it matter?? #EcoEvo #Ecology #Evolution 🧪

Eppley et al (2026) "We believe that acknowledging limitations and assumptions of current definitions of sex will lead to more accurate science." 🧪

V. important perspective piece by @madeline-eppley.bsky.social & @andylee.bsky.social on biological sex and why a lack of scientific consensus should not be used to dictate human rights doi.org/10.1111/ele.... 🧪

Hey all @shaykeretz.bsky.social is a wonderful freshwater bivalve-focused colleague and she is managing a great new project partnering USFS with UGA, led by Dr Rachel Toczydlowski!

Did you know that the bees that need saving are NOT honeybees? Honeybees are the dairy cows of bees. People brought them over from Europe to make us honey. The problem with honeybees, esp in resource-limited ecosystems (like hey! cities!) is that they compete with our native bees for food.

New WISE Lab Paper! The concept of cultural keystone species, revisited through the eyes of Indigenous Peoples

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.

omg another paper with @madeline-eppley.bsky.social and @allydefduf.bsky.social accepted!!! Extra proud of this one (and also really nervous for it to come out). We thought a lot about how biologists define sex in our research. Out soon in Ecology Letters!

Paper accepted!!! Beyond honored to have worked with fellow queer ECRs (@madeline-eppley.bsky.social, @allydefduf.bsky.social and others not on bsky) to critically examine our field's relationship with the queer community, and how we can leverage Queer perspectives to conduct more accurate science!!

Being faculty in the US in 2026 means your meetings with students about their grad school apps also includes checking in to make sure none of their family has been kidnapped by ICE and wtaf is this world we've made

one more week to apply for a 4-years PhD position with me to work on the macrogenomics of sea warming. Deadline: Jan 18th 2026 #MarineGenomics #EvolutionaryBiology #PopGen #Bioinformatics #conservationgenomics #consgen #conservationgenetics

US faculty, your immigrant colleagues are lonely and scared right now. And they can no longer share how they feel on social media without fear of harming their immigration status. Check in on them.

In this new study that emerged from a great collaboration led by @morganefrapin.bsky.social and Ehsan Pashay Ahi, we dig into the molecular mechanisms of density-dependent effects in Atlantic salmon, specifically in their hypothalamus (a key site for endocrine regulation). A couple of points below👇

Alright scientists! It's that time again! Time to sign up for Skype a Scientist's spring semester. Want to get matched with a classroom in 2026? Sign up now 🥰 docs.google.com/forms/d/e/1F...

THERE ARE NO JOBS IN ACADEMIA! NO JOBS! DOZENS OF HYPER QUALIFIED APPLICANTS PER JOB!

Did you really go to grad school if you didn’t also become a climber???

I am still actively looking for postdoc positions — please lmk if you (or your friends and colleagues) need a hardworking postdoc with field, lab, and bioinformatic skills! I am broadly interested in evolution in the ocean, conservation and population genetics, and rapid evolution.

Successfully added a few letters to my name last month!!! Truly could not have done this with our villages upon villages 🫶🏼

TODAY at 1pm eastern, we're going to be talking about snails under the sea and how they're reacting to climate change with @andylee.bsky.social ! These sessions are Q&A so it's all about what YOU want to know! Join us for free at 1! RSVP link here: givebutter.com/DALmWY

We’re excited to be collaborating with @skypeascientist.bsky.social for their free livestream on December 4th at 1 PM EST featuring researcher Andy Lee! Register here for your chance to talk with Andy about his research on sea snails & climate change: sciencejournalforkids.org/articles/les....

Leading up to the livestream, make sure to read our article, adapted from the work of @andylee.bsky.social & other researchers about how sea snails that have migrated north are adapting to their new habitat: www.sciencejournalforkids.org/articles/why...

i’m defending my phd in a couple weeks!!!! lmk if you’d like an invite/link

For those of you dismayed by a certain Billionaire making statements that seem to not prioritize a habitable planet, just want ya’ll to know that there’s a whole lot of us non billionaires that are working really hard on a future that prioritizes people, health, and planetary sustainability. 🌏

lecture today was about genetic drift and small populations, and one of the students said “diversity type shii” so i think they’re understanding the material

Why are some sea snails moving north? My first publication has been translated into a kid's article!! www.sciencejournalforkids.org/articles/why...

If you are a federal scientist in the US and have a been served a RIF notice during the shutdown, experts say this is illegal. you can contact Ranking Member Zoe Lofgren (D-CA) confidentially via the Science Committee Democrats’ Whistleblower form democrats-science.house.gov/contact/whis... 🧪.

how is it 2025 and we still have to remind scientists that science IS POLITICAL scientist are PEOPLE and some of us would really like to keep having rights!!!

Excited for this to finally see the light of day - new preprint from my lab, where we present a fast, accurate maximum likelihood tool to estimate population structure, called MULTICLUST. We extend the model of Alexander et al 2009 (ADMIXTURE) to multiallelic data. www.biorxiv.org/content/10.1...
