From North Asia to South America: Tracing the longest human migration through genomic sequencing
Genome sequencing of 1537 individuals from 139 ethnic groups reveals the genetic characteristics of understudied populations in North Asia and South America. Our analysis demonstrates that West Siberi...

The genetic architecture of and evolutionary constraints on the human pelvic form
Human pelvic evolution following the human-chimpanzee divergence is thought to result in an obstetrical dilemma, a mismatch between large infant brains and narrowed female birth canals, but empirical ...

Leveraging ancient DNA to uncover signals of natural selection in Europe lost due to admixture or drift - Nature Communications
Large-scale ancient DNA (aDNA) studies offer the chance to examine genomic changes over time, providing direct insights into human evolution. Here the authors use aDNA from 708 European samples to ide...

I'm so excited to share this new paper (with my great advisor @nanditagarud.bsky.social), on selective sweeps in gut bacteria. In this long thread, I’m going to go over our results, but I also want to highlight some of the incredible work that set the stage for us
