John Postlethwait contributes to Research Areas I and III by addressing how the genomes of host cells respond to microbiomes during development and during evolution. He is probing those two questions by investigating how cells of the digestive tract and other tissues react to different microbial communities over developmental time and over evolutionary time. His lab studies fish from many habitats with different environmental microbes, including the Antarctic.
