One of the most exciting works of my career, years in the making. We used high-throughput precision genome editing to test the fitness effects of thousands of natural variants. Our findings challenge the long-held assumption that common variants are inconsequential.

Massively parallel interrogation of the fitness of natural variants in ancient signaling pathways reveals pervasive local adaptation

Great new postdoc fellowship for foundational plant research.
If you’re into genetics and genomics of plant reproductive evolution or adaptive convergence (incl in the cool and charismatic nightshades!) I’d be happy to talk about possible projects!

Human-mediated land-use and climate change occur simultaneously, but how do they interact to shape adaptive dynamics? Super excited to share the first paper from the Kreiner lab, led by postdoc extraordinaire @rpineau.bsky.social

We’ve just published a paper on Senecio showing that ecological speciation and mutation-order speciation can act together rather than as an either/or. Congratulations, Maddie James and MC Melo!
