Professional Title: 
Scientist & Team Lead

Dr. Bailey’s research addresses the role of soil physical structure on microbially-mediated soil C cycling. This research includes a focus on the role played by water as a solvent and transport agent in soils, and uses a suite of molecular chemical and multi-omic approaches to answer questions about the stability and vulnerability of soil carbon. Her research is conducted both in the field, where landscape processes are observed and soils sampled, as well as in the lab where studies occur in controlled microcosms.
