We are destroying species' habitats, leading to a mass extinction event. This habitat destruction also reduces the genetic diversity _within_ species. Our latest work develops quantitative models to predict how much genetic diversity has been and _will be_ lost. 🧬🧪🧵 www.pnas.org/doi/10.1073/...

Have you ever wondered how many archaic populations contributed DNA to modern humans? We know about Neanderthals and Denisovans, but the fossil and genetic evidence suggests a much more complex history! www.biorxiv.org/content/10.6...

Based on a 2025 study by the great @jazlynmooney.bsky.social & colleagues

New for @undark.org On: "The Birthday Paradox," the transatlantic slave trade, ancestral bonds, and the hidden power of statistics. "Family is family, whatever our genetic relationship. Impressively, the birthday paradox study captures this possibility." undark.org/2026/02/27/o...

Excited that our work was featured on the local (Bay Area) news for their Black History month series. Interview with Noah and clips from my interview with @dornsife.usc.edu and CGSI talk in the article below www.nbcbayarea.com/discover-bla...

New paper! From Sam Snodgrass and @genomeofforrest.bsky.social, w/ @druncie.bsky.social, @gcbias.bsky.social, and a collaboration with Andres Moreno and @santiagogmm.bsky.social. Can we quantify the impact of humans on maize dispersal? Plant yourself in a comfy chair and lend me your ear: 1/10

In celebration of #BlackHistoryMonth let’s learn more about Marie Taylor, a plant biologist and chair of Howard University’s Botany Department. Love her focus on photomorphogensis and using light microscopy on living plants! 🌱 en.wikipedia.org/wiki/Marie_T...

Check out this preprint. Tianlin Duan led this project during her postdoc with me and Mike Whitlock. It’s got a lot of stuff in it for those who are interested in the genomics of adaptation

"Instead of unifying different strands of animal behavior research, Sociobiology amounted to an individualistic effort aiming to supersede ongoing developments in the field. Wilson neither provided the theoretical cohesion nor inspired the social unity necessary for the foundation of a discipline"

Cool new work from Sophie Buysee w/ @jeffreykconner.bsky.social on how different Arabidopsis thaliana populations respond to drought.

Differentiation for drought strategy but conserved plasticity to heat and drought in locally adapted populations of Arabidopsis thaliana https://www.biorxiv.org/content/10.64898/2026.01.07.698234v1

Less than a month before my debut book "What We Inherit" gets released! You can place pre-orders now: press.princeton.edu/books/hardco... Lucky to have gotten to collaborate (and argue) with Sam Trejo for the last 5+ years on this.

Carlson et al. build a mathematical model considering how genotype-by-environment interactions can maintain variation and parametrize their model to test its applicability to real mutualisms. Read now ahead of print! www.journals.uchicago.edu/doi/10.1086/...

So what's the alternative to grantwashing you ask? We offer several ideas, including one by Alondra Nelson that borrows from the structure of the Human Genome project to dedicate 3-5% of R&D funding from emerging technologies to safety and ethics research. www.science.org/doi/10.1126/...

Hey all, I reached out to the PO of my NIGMS MIRA to ask if the gov't shut down, and rescheduling of study sections, might allow for some accommodation to the standard rule that PIs cannot resubmit a MIRA while their MIRA (or other RPG) is under review (waiting in scores or summary statements) 🧪

What a beautiful paper! www.nature.com/articles/s41...

Grateful to share our paper on gene-specific selective sweeps in human gut microbiomes, now out in Nature! It has been a joy to work with @rwolff.bsky.social, whose insights and hard work made this possible. www.nature.com/articles/s41...

The Influence of Demographic History and Genetic Architecture on Complex Traits via Runs of Homozygosity https://www.biorxiv.org/content/10.64898/2025.12.17.694908v1

Preprint online right before the holidays! Excited to share the first piece of work from the Zhang Lab, led by my absolutely stellar postdoc Michelle Kim! In this work, we ask how admixture, selection and demography shape complex trait genetics and GWAS performance www.biorxiv.org/content/10.6...

We are thrilled to announce the first official release (v0.1.8) of #𝗯𝗲𝗱𝗱𝗲𝗿, the successor to one of our flagship tool, #𝗯𝗲𝗱𝘁𝗼𝗼𝗹𝘀! Based on ideas we conceived of long ago (!), this was achieved thanks to the dedication of Brent Pedersen. 1/n

In small sample sizes and understudied populations, our GRM-based approach outperforms existing methods, all of which rely on GWAS summary statistics. Unlike GWAS, constructing GRMs does not require biobank-scale data, and in-sample GRMs are inherently robust to portability concerns. (5/6)

Excited to share work from my postdoc with @docedge.bsky.social and collaborators Matt Pennell and @jgschraiber.bsky.social, newly out over the weekend: www.biorxiv.org/content/10.1... (1/6)

Observational epidemiological studies can mitigate genetic confounding with the genetic relatedness matrix https://www.biorxiv.org/content/10.1101/2025.11.24.690292v1

Howell et al. used WGS of wild-caught deer mice from two islands and one mainland location in British Columbia to investigate chromosomal inversions and non-equilibrium demographic history of this species. 🔗 doi.org/10.1093/molbev/msaf254 #evobio #molbio #peromyscus

"What James Watson got wrong about DNA" By the great Sohini Ramachandran (@sramach.bsky.social) and your boy for The Boston Globe (@bostonglobe.com). www.bostonglobe.com/2025/11/14/o...

Amazing to have a byline with @cbo.bsky.social - read our take on Watson’s ultimate legacy in the Boston Globe. Will be in Sunday’s print edition.

Kudos to our superstar grad student @sophiejwalton.bsky.social! One of the most interesting and surprising (at least to me) studies I have been involved in. Very curious to know what people think of it! @benjaminhgood.bsky.social

Excited to share some new work led by grad student Sophie Walton (w/ @petrovadmitri.bsky.social). We used in vitro gut communities to study how natural selection acts on strains of the same species as they compete within larger communities. Check out Sophie's thread below for details!

Super excited that the bulk of my PhD work is now preprinted! Here we used whole-community competition, or coalescence, experiments to quantify selection acting on genetically diverged strains within larger communities. (1/n) www.biorxiv.org/content/10.1...

Community coalescence reveals strong selection and coexistence within species in complex microbial communities https://www.biorxiv.org/content/10.1101/2025.11.06.687011v1

@brielin.bsky.social's fantastic work on causal gene network inference from Perturb-seq is published! We estimate total causal effects using guides as instruments, then deconvolve into direct & mediated effects with a directed analog of graphical lasso. Deets: nature.com/articles/s41467-025-64353-7

How do GWAS and rare variant burden tests rank gene signals? In new work @nature.com with @hakha.bsky.social, @jkpritch.bsky.social, and our wonderful coauthors we find that the key factors are what we call Specificity, Length, and Luck! 🧬🧪🧵 www.nature.com/articles/s41...

Millions of specimens, centuries of history — all coming to life online 🌿✨ After nearly four years of dedicated work, our digitisation project is entering its final stretch — and we’re gearing up for an amazing finish by March 2026.

America’s still terrified of powerful women in politics. It’s pure misogyny baked into the system. Add race to the mix and it’s on a whole different level of hate that most won’t even admit. Time to get over that shit! Let’s take a step forward on Tuesday. [video: @mollyjongfast.bsky.social ]

Science is intertwined with eugenics; eugenic ideologies continue to negatively impact #Indigenous communities to this day. In the October issue of #GENETICS, @jazlynmooney.bsky.social and colleagues offer a timely and important reminder on the perils of eugenics. buff.ly/1Q5r3XF

This is one of my favorite webinar series. Working on polyploidy? Sign-up to give a talk! If you are a grad student or postdoc, this is a really great opportunity to get feedback and connect with others.

How does life evolve to adapt to modern cities? Out now in Science, my PhD work with @lindymcbr.bsky.social uncovers the ancient origin of the “London Underground mosquito” – one of the most iconic examples of urban adaptation. 🧵(1/n) @science.org www.science.org/doi/10.1126/science.ady4515

Proud of the latest edition of my free intro biostats book. gitrepo: github.com/ybrandvain/b... book: ybrandvain.github.io/biostats/ Not complete but at a good point to take a break, and I think its quite usable dm me with comments , ideas etc
