Our paper on indirect assortative mating is now out in @natcomms.nature.com! In it, we provide refined definitions of terms used to explain partner similarity, develop statistical models, and find evidence of surprisingly high social homogamy for education.

📣 Latest from the lab: Performance of deep-learning-based approaches to improve polygenic scores www.nature.com/articles/s41...

Its thought deep learning will substantially improve PGS but the reality is MANY have tried but no/little gain has been seen so far. Here we report our negative results.

Happy to share a new preprint, to which I provided a minor contribution.

Using genetic data from ~100k human embryos, we found ~1k that were haploid or triploid.

We describe a thorough characterization of these embryos, with many interesting findings 🧵

Did you know you can get DNA viruses from standard blood WGS done in large biobanks? (i didn’t). One point in favor of WGS vs WES

Yet another nice paper from Yuki’s group

Nice analysis by PRS company Genomics plc, quantifying the potential reduction in mortality due to PRS screening. Assuming people at high risk for 7 diseases get early access to prevention/detection, they estimate saving 95 lives for each 100k people.
