Excited to share our work on bacterial immune signaling! Our preprint reveals how RNA-guided Cas13 cleaves host tRNAs to generate small-molecule messengers that activate 2TMβ, linking RNA recognition to membrane damage and phage defense. 1/11

I’m happy to share our study out in Microbiome! link.springer.com/article/10.1... Knowing that coculture interactions often disappear in larger communities, we used cocktails of phages to study vitamin exchange interactions within enrichment cultures.

My final postdoc project is out today in Nature! We show microbes co-migrated with humans out of Africa; three independent methods agree, and timing matches archaeological / genetic evidence (Fig. 4c). Seeing Fig. 4c for 1st time was one of my most memorable "eureka" moments! doi.org/10.1038/s415...
