Research Summary

Soil microbial responses to anthropogenic disturbance and of microbes’ roles in mitigating disturbance effects; nitrogen transformations in agricultural and urban soils; microbe-mineral-plant interactions and biological crusts that form and stabilize soils in acid mine drainage impacted areas; and carbon and nitrogen fixation by bacterial communities in soil crusts and in bedrock-regolith interface zones.
