Biogeochemistry Research at WSU

Soil biogeochemistry considers the interactions between soil particles and the plants, microbes, and chemicals that control the fate of contaminants and nutrients in soils.

My research emphasizes linking the function and phylogeny of the soil microbiome, specifically with regard to interactions with plant roots and impacts on metal bioavailability and plant uptake. The soil microbiome is key in the biotransformations of many micronutrients and metals in the rhizosphere; these consortia and the mechanisms involved, drives my work.
