We work on the ecological and evolutionary genomics of beneficial plant-microbe symbioses. We use legumes and nitrogen-fixing bacteria to explore questions about how plants structure their microbiomes and enforce mutualistic microbial behavior, how plant-microbe interactions evolve during the invasion of novel habitats, and the role of microbial communities in plant biodiversity.

We also work on free-living nitrogen fixers, with a focus on bioenergy crops to understand connections between microbial communities, plant traits, and ecosystem functions.
