Interests and Expertise

Raven works at the intersection of microbial ecology and biogeochemistry with the goal of understanding how communities of microorganisms create and respond to changes in their environment. Her research goals encompass three major objectives: 1) understanding how disturbances alter microbially mediated nutrient cycling, 2) identifying connections between microbial phylogeny and microbial processes, and 3) manipulating categories of microbiome assembly to study the influence on functional groups. She uses field and lab studies to determine the consequences of land use change on aquatic microbiomes and seeks to understand which concepts and parameters best enable us to predict their responses under environmentally-relevant conditions. The long-term goal of her research is to couple microbiome research with biogeochemical dynamics in a way that will expand both our conceptual and applied capacity for ecosystem stewardship.
