I am excited to share my first paper, our new preprint: www.biorxiv.org/content/10.6... with @arbelharpak.bsky.social and @docedge.bsky.social. Family GWAS provides direct genetic effect estimates and is increasingly important. But how much can we trust these estimates? (1/15)

(1/9) Our work (with @xliaoyi.bsky.social @arbelharpak.bsky.social) exploring the role of genes that escape X-chromosome inactivation in shaping the genetic architecture of sex-specific traits is now officially out in Molecular Biology and Evolution! academic.oup.com/mbe/article/...

Our work on the generalizability of polygenic scores (PGS) from the @arbelharpak.bsky.social Lab is now officially out! We examine the accuracy of PGS predictions at the individual level. We make 3 observations that expose gaps in our understanding of PGS “portability.” rdcu.be/e0LAr (1/27)

Excited to share our new preprint from the @arbelharpak.bsky.social Lab! How do recruitment into genetic studies and study characteristics impact what we infer about the genetic bases of traits, and what are the consequences? (1/21) www.biorxiv.org/content/10.6...

1/13 In a new preprint, we (with @xliaoyi.bsky.social‬ in the ‪@arbelharpak.bsky.social‬ lab) find that expression from the “inactivated” X (Xi) is consequential for both female-male differences in gene expression and variation among females in disease and physiology: www.biorxiv.org/content/10.1...

Led by Brieuc Lehmann, we have a paper on relatedness and ARG! Closely related to my PROBGEN talk on Friday.

Think of a polygenic score you care about. Are direct genetic effects driving variation among people in this predictor? Or perhaps other, confounding factors? We at the @arbelharpak.bsky.social & @docedge.bsky.social Labs developed a method to tackle this question. [1/n]

I am excited to share the first first-author paper of my PhD describing work with Changde Cheng, Mark Kirkpatrick and @arbelharpak.bsky.social has been published at AJHG! We ask if sex-differential gene expression drives sex-differential selection in humans. (1/14) www.cell.com/ajhg/fulltex...
