Research and Professional Interests:

Hosts rely on a healthy microbiome for optimal growth and development. While the microbiome is crucial for functional immune system development, immunity has also been shown to influence microbiome composition in a manner that prevents dysbiosis.

Plant roots are analogous to the animal gut as both are important sites of nutrient acquisition and microbial activity. We use the plant model system, Arabidopsis thaliana, to study the role of innate immunity in establishing a healthy root microbiome. We use a combination of NextGen sequencing, microscopy, and genetics to study the mechanisms required for distinguishing between beneficial and pathogenic bacteria in a manner that modulates bacterial growth.
