I’m interested in studying plant-microbe interactions from a molecular ecology and evolutions lens. Particularly, I want to explore the ecological and evolutionary dynamics of microbial communities under different host background as selection environments, and understand how they affect individual or microbial community adaptation. I am co-advised by Cara Haney.
