I'm looking for PhD students to join the lab starting August 2026. We study the evolution of insect chemical signals so if you're interested in evolutionary biology, chemical ecology, molecular biology, behavior, or genetics, this could be a good fit for you! More info here: tinyurl.com/mrxchwfm

How many chromosomes can an animal have? In our paper out now in @currentbiology.bsky.social we show that the Atlas blue butterfly has 229 chromosome pairs- the highest in diploid Metazoa! These arose by rapid autosome fragmentation while sex chromosomes stayed intact. www.cell.com/current-biol...

Out today in @genetics-gsa.bsky.social #G3journal - our manuscript describing biases in summary statistics like genetic differentiation (Fst), diversity (pi), Tajima’s D, and estimates of theta, migration rates, and divergence times when not accounting for ghost gene flow. doi.org/10.1093/g3jo...

FlyBase needs your help! We ask that European labs continue to contribute to Cambridge, UK FlyBase, whereas US and other non-European labs can contribute to US FlyBase. For more information and how to donate: wiki.flybase.org/wiki/FlyBase...

Thanks so much to @trstngnthr.bsky.social for seeing this through. This paper started like 7 or 8 years ago when I was still at Temple!

My company is hiring a computational biologist! This role is the same position as mine, and will involve building genomic prediction models, some bioinformatics, and a lot of independent research on developing new methods to improve our crop development initiatives. www.linkedin.com/jobs/view/42...

Incredibly proud of this work where we developed a method for understanding the information contained in millions of genomes. Another example of NIH funded research.

Excited to finally have the pre-print up for this work on evolutionary rescue from my PhD at UBC! Previous theoretical work on the effects of negative density-dependent growth on evolutionary rescue has uncovered inconsistent results, leading to an incomplete understanding of its influence.

This began as a @jgi.doe.gov Community Science Program (CSP) project in 2017 with the goal of uniting the diverse sorghum breeding and mapping populations in the framework of a 'pangenome'. Thanks to a huge efforts across many stakeholders, the article was preprinted today. A 🧵 w/ what we found:

When I was little, the U.S. military came to our home at gunpoint and took me and my family away. We were imprisoned for years in barbed wire camps simply because we were Japanese American. I have spent my life telling that story, hoping it would never be repeated.

My talk from this year's probgen is finally out. Where do linear mixed models and random effects come from? They emerge from *mutations* on Ancestral Recombination Graphs.

Please share! Our lab is recruiting a PhD student to join us starting fall 2026. Our group is broadly interested in plant molecular evolution and comparative genomics. More info about our lab and grad programs at Colorado St. is available on our lab website. sites.google.com/site/danielb...

Staff scientist position (computational): I am looking for a computational scientist to join my genomics lab at Stanford. They should have an outstanding skillset in ML/statistical methods for genomic applications, postdoc experience and a strong publication record. #sciencejobs

I'd like to share a new method my grad student Linh and I have been developing called Topsicle. Do you have long read sequencing data and wondered what the telomere length of your organism is? If you're wondering then Topsicle is the tool for you! github.com/jaeyoungchoi...

Schlichta, Peischl & Excoffier reveal how purifying selection on deleterious mutations impacts diversity: while codominant variants create diversity dips, recessive mutations can preserve diversity in bottlenecks through pseudo-overdominance. 🔗 doi.org/10.1093/gbe/evaf107 #genome #evolution

Very happy (and frankly relieved) to see this paper finally out in peer-reviewed form. (Preprint was posted in August 2021, but this is the world we live in now). rdcu.be/erMk6

Interested in the evolution of molecular interactions ? We are recruiting a new PhD student with a background in proteomics to study the diversification of the receptor-ligand interaction controlling plant self-incompatibility. --> details here : initiative-excellence.univ-lille.fr/fileadmin/us...

I am delighted to be starting as an assistant professor in the Department of Molecular Genetics & Microbiology at the University of Florida in January 2026. The lab is broadly interested in the functional, developmental, and evolutionary genetics of cell types and organs across flies and beyond 🪰🧬

I'm very excited to share the first research paper from my lab! My postdoc Surbhi led this amazing study. We combined genomics, evolution, and biochemistry to explain how telomeres evolved in monkeyflowers. If you're into unusual chromosome evolution please read! @plos.org tinyurl.com/bdeku44x

ACLU: “Trump's deployment of federalized National Guard troops in response to protests is unnecessary, inflammatory, and an abuse of power. By taking this action, the Trump administration is… recklessly undermining our foundational democratic principle that the military should not police civilians"

Genome size is surprisingly variable even WITHIN species. Dunja Lamatsch, Martin Haase, Maria Pilcher, and I use flow cytometry to show a nice example of this variation in this new paper, perhaps connected to a resolving whole-genome duplication, in our snails. 💜🐌🧬 doi.org/10.1098/rsos...
