"How two hybridizing monkeyflowers resist phenotypic homogenization" I'm very happy to share this. We would really appreciate your feedback!

Slide with the title and authors list of a manuscript along with illustrations of the monkeyflowers Mimulus guttatus (left) and Mimulus glaucescens (right). In the background, a Manhattan plot with outlier loci and QTL locations. Title: Maintenance of phenotypic divergence in two sympatric monkeyflowers with weak reproductive isolation Authors: Henry Arenas-Castro, Cage Cochran, Quinn Evans, Hongfei Chen, Jenn M. Coughlan Manuscript: bioRxiv, 10.64898/2026.07.28.741377

So proud of this manuscript- lead by the fantastic @henryarenas.bsky.social with two undergraduates (Cage Cochran and Quinn Evans) each doing a Herculean effort during their honors theses, and Hongfei Chen helping out tremendously with lab work. www.biorxiv.org/content/10.6...

Comparative population genomics reveals adaptive convergence in two Drosophila species across global environments

Comparative population genomics reveals adaptive convergence in two Drosophila species across global environments

Li et al. compare global genomes of D. melanogaster and D. simulans across evolutionary timescales. They show that 12%–17% of adaptively evolving genes are shared between species, with minimal overlap at the nucleotide level, revealing a hierarchical repeatability of adaptation.

Beyond providing insight into the centromere paradox, this work demonstrates that complete chromosome reconstruction is now possible from wild-caught flies, opening new opportunities for population, functional, and quantitative genomics in Drosophila. Preprint here: www.biorxiv.org/content/10.6...

A conserved architectural domain shapes centromere evolution in Drosophila

Centromeres ensure faithful chromosome segregation despite being embedded within rapidly evolving repetitive DNA, a contradiction known as the centromere paradox. While centromere identity is defined ...

New preprint on the effect of ancient admixture / structure on genealogical trees. I introduce a new way of summarising reconstructed genealogies that captures a clear signal of ancient gene flow into the ancestors of modern humans. Feedback welcome!

Avocados come in 2 varieties - A-types start each day female and switch to male midday. B-types do the reverse. In work just published from the last chapter of my PhD, we show this system evolved 40+million yrs ago and is regulated by alleles of 1 transcription factor www.pnas.org/doi/10.1073/...

We are deeply saddened to share that Michael Freeling passed away on 7/20/2026 after a year-long battle with cancer. Our deepest condolences go to his family, friends, colleagues, and the many students he inspired. We will share additional memorial information soon.

We are very sorry to share the sad news that Michael Freeling passed away on 7/20/2026 after a year long battle with esophageal cancer. Mike was a long-time faculty member in the Plant and Microbiology Department at University of California-Berkeley, a groundbreaking plant geneticist, and an inspiring teacher and mentor to over two dozen Ph.D. students, four dozen postdocs, and countless undergraduates. He was best known for pioneering work on maize anaerobic metabolism and gene regulation, transposon biology, developmental genetics of the maize ligule, and the discovery of biased gene retention following whole-genome duplications in plants. Mike was hired by UC-Berkeley as an assistant professor straight out of graduate school in 1973, and he was promoted to Associate Professor in 1979 and to full professor in 1984. He was selected as a Guggenheim Fellow in 1980, elected to the National Academy of Sciences in 1994, and won the McClintock Prize for Plant Genetics and Genome Studies in 2017. Mike taught genetics, comparative genomics and scientific reasoning to our graduate students, and he also taught a popular genetics course for non-majors that had various titles over the years but was affectionately known as “Genetics for Poets.” Our deepest condolences go out to his family, friends and many colleagues.

How do transposons jump when they’re released from host control? I babysat two chromosomes for 2 years, making sure they are ok without most piRNAs. Here’s what we found & excited to share my 1st postdoc paper: “piRNA loss unleashes episodic transposition bursts” www.biorxiv.org/content/10.6...

piRNA loss unleashes episodic transposition bursts

In Metazoa, transposon expression is suppressed by the piRNA pathway, and disruption of this pathway leads to rampant transposon expression. However, it remains unclear whether increased transposon ex...

Hey team - it’s looking very likely that I’ll be hiring not one but two four year postdocs! We’re a fun lab with tons of theoretical and applied pop gen projects - broadly in polyploid, conservation, and human evo. Competitive salary, sunny San Diego! Do share with your about to defend grads!
