Dr. Melissa A. Cregger is a staff scientist in the biosciences division of Oak Ridge National Laboratory.

An ecologist, Cregger is broadly interested in understanding microbial community dynamics across ecosystems, and how changes in microbial community structure may influence ecosystem-level processes. Specifically, she is interested in understanding the potential for changes in microbial diversity and composition to influence the health of associated host organisms and to alter large-scale nutrient fluxes. Her research spans scales from the molecule to the ecosystem level, taking advantage of modern techniques to fully understand microbial interactions, Oak Ridge National Laboratory states.

Cregger received her doctorate in ecology and evolutionary biology in 2012 at the University of Tennessee.
