My research emphasis is on linking the function and phylogeny of the soil microbiome, specifically with regard to the interactions and impacts on metal bioavailability. Whether the context is micronutrient availability in the rhizosphere, which confers plant growth promotion and crop enhancement, or in the context of contaminated systems where bioremediation and bioaugmentation are the best options to remediate heavy metals polluted sites, the soil microbiome is key in theses biotransformations. Understanding the consortia of organisms and the mechanisms involved drives the work in my lab with a wide array of biochemical and molecular techniques.

Symposium Addresses the Science of the Rhizosphere
According to Tarah Sullivan, Washington State University, “the specific metabolic activities and signaling that takes place within the microbiome and between the microbes and their host plants is a rapidly growing focus area of scientific understanding.” Her research seeks to bridge the gap in knowledge about the functional role of microorganisms associated with the roots of plant species, with specific focus on metal chelating abilities of members of the plant and soil microbiome.

Can Good Fungi Restore Bad Soil?
Tarah Sullivan is fascinated by fungi, especially the ones in agricultural soils that offer hope for addressing toxicity issues by transforming harmful metals. Read More
