New preprint out! The Punan of Borneo offer rare windows into what happens molecularly when a hunter-gatherers transitions to a settled lifestyle, and the answer is: a lot and fast. Deep gratitude to the communities for their trust & participation. Feedback welcome 🙏 www.biorxiv.org/content/10.6...

Rapid convergence toward an agriculturalist regulatory landscape following lifestyle transition in Bornean hunter-gatherers

The transition from hunter-gatherer to agricultural lifestyles is one of the landmarks in the history of human societies, but its phenotypic and immediate molecular consequences remain poorly understo...

Why do schizophrenia GWAS signals look so flat across the genome? In our recent preprint, we explored why psychiatric disorders — and, more broadly, brain-related traits involving the central nervous system — appear to have unusual genetic architectures. 🧵1/n

Gene expression changes aren’t just about mean shifts — variability shifts matter too, especially for aging. We're thrilled to introduce QRscore, a flexible non-parametric framework for detecting shifts in mean and variance across conditions. doi.org/10.1016/j.cr...

Excited to share a new preprint with @jnovembre.bsky.social ! We use a combination of population genetic theory, simulation, and data analysis to ask: how does study design in genetic studies (including biobanks) impact the discovery of rare, deleterious variants?

It's a common knowledge that EPAS1 is enriched, and pos selected, in Himalayan highlanders. But i keep being astonished by the peaked frequency in the Himalayan highlander population given relatively recent split with the Han. Do we know the selection coefficient of these EPAS1 alleles in the pop?

Optimist: The cup is half full. Pessimist: The cup is half empty. Population geneticist teaching drift: Sample with replacement the atoms of water in this cup until the next cup is full and assume the total number of atoms stays constant.

Optimist: The cup is half full. Pessimist: The cup is half empty. Population geneticist: The cup is either a quarter full or overflowing and I can never remember whether there's a factor of two for haploids or diploids. bsky.app/profile/hutc...
