Researchers across the country are turning to side hustles to fund their work. Behind the cuts sits a bigger shift: whether American science can still sustain durable research capacity. @lindseydcameron.bsky.social and I examine the stakes in a new piece @science.org: www.science.org/doi/10.1126/...

I’m looking to hire an NIH funded postdoc to join our lab here at Davis (please RT). Ongoing areas of interest include:
1) polygenic signals of selection from time series, ARGs, GWAS, etc
2) The interpretation of GWAS, polygenic scores, & sources of confounding
