💥OUR LAB IS HIRING!!💥 We are hiring a research assistant/lab manager to assist with managing our axolotl colony and enabling some kick-ass science! Looking for high levels of organization, collaboration, problem solving and curiosity. Application link: tinyurl.com/3tpvphpm #SciJob #JobAlert

1🧵 Excited to share my first PhD paper, published in @dev-journal.bsky.social What if fish gills —often overlook —hold secrets about development, patterning, and function? We uncovered how early patterning shapes adult gill architecture. journals.biologists.com/dev/article/... #DevBio #Zebrafish

Come be my colleague in the department of neuroscience at OSU. We are hiring for an open rank tenure track faculty position in several focus areas. neurojobs.sfn.org/job/39081/te...

Just keep thinking about fish

Now published @natecoevo.nature.com with @annika-nichols.bsky.social, our latest on the evolution of 𝘴𝘭𝘦𝘦𝘱 across 𝟲𝟬 𝘀𝗽𝗲𝗰𝗶𝗲𝘀 of cichlid fishes! doi.org/10.1038/s415... with members of the @schierlab.bsky.social and Salzburger labs, as well as the burgeoning Shafer lab @uoftcellsysbiol.bsky.social

Proposed cuts to the National Institutes of Health and the National Science Foundation “would cause immense and largely irreversible damage to the successful American scientific enterprise,” write Jerry Kaplan and Dana Carroll in an op-ed.

Happy to announce our paper comparing embryonic gene expression between C. elegans and C. briggsae, work led by Christopher Large with Rupa Khanal and in collaboration with Junhyong Kim and Bob Waterston. www.science.org/doi/10.1126/...

We are excited to announce the winner of the Chi-Bin Chien Award, Dr. Victoria Deneke! See more about Dr. Deneke and the CBC Award here: www.izfs.org/news/congrat... @impvienna.bsky.social @vdeneke.bsky.social

To dissect the gene regulatory networks used to build organisms, we need Perturb-seq-like tools that work in whole animals. For this purpose, we developed MIC-Drop-seq, a tool that couples high-throughput CRISPR in zebrafish embryos with single-cell RNAseq. www.biorxiv.org/content/10.1...

The Department of Human Genetics at the University of Utah is sponsoring the Rising Stars in Genetics and Genomics symposium! - We are seeking nominations bu June 1. - September 18-19, 2025 - Please share with the star postdocs that you know. docs.google.com/forms/d/e/1F...

Happy to share a new preprint from my lab! We characterize the on/off kinetics, light dosage-dependence, and more for a suite of optogenetic signaling activators in zebrafish embryos 💡 www.biorxiv.org/content/10.1...

This is an exciting time for reproductive research in fish, let's get together and talk about it at the Reproduction session!🪺 If you are on team germ cells and gonads, please RT and send in abstracts @marymullins.bsky.social @yanivelkouby.bsky.social @erezraz.bsky.social @zebrafishrock.bsky.social

So, everyone knows the story about the time the 5th Dalai Lama wrote the Editor to complain that Ernst Haeckel hadn’t cited his work from 200 years earlier? Right? Right? Coming soon…. #devbiol #SciHist #TheLongBibliography

Hello everyone, the MBL Gene Regulatory Networks for Development course still has openings for its 2025 offering, Apr 6-18. We’d love to receive some more applications! The deadline is Jan 3, but if you start the application by then and get us the letters later, we will be happy to consider you!

New preprint out now! The history of some RNA virus lineages that infect vertebrates might date back to our invertebrate ancestors. Read more here: biorxiv.org/cgi/content/...

Beethoven, one of the most celebrated musicians in history, scored unremarkably on the musicality-related polygenic index, ranking between the 9th & 11th percentile based on modern samples. In our paper we explain why this is no surprise & how it offers a nice example for teaching complex genetics.

Today is the final lecture of my 7th (and possibly last) time teaching undergraduate Cell Biology. Over the years 2,554 students have finished my class! 20+ years ago, this class convinced me to be a biologist, and I hope I passed that spark along to some of my students 🧬🔬🦠🧑‍🔬

I took this picture of the night sky over this neat rock formation while camped out in the eastern Sierra back in October. I loved how the milky way seemed to erupt from the rocks. #landscapephotography #astrophotography #nature #photographer #nikon

I loved working on this future-focused review with an absolute Murderer's Row of smarties in the DNA recording field. Hope we can all meet in person some day!

This short graphic novel about Fish Sex Determination from Sophia Breslin, John Postlethwait, & Thomas Desvignes @notothentoma.bsky.social is AMAZING! blogs.uoregon.edu/fishsexdeter... 🧪🐠🧬

How does the testis age? Our first paper on this topic is now out in Development. Spermatogonia become less able to contribute to sperm production in older males, and in some cases we see really wild gene expression, like pluripotency genes and even ovary genes! doi.org/10.1242/dev....
