Sherri L. Johnson, Research Ecologist

- Ph.D., University of Oklahoma
- USDA Forest Service Scientist
- A research ecologist studies streams and lakes to explore both who lives in the water and how forestry and year to year climatic variability impact the water quality and water as habitat for biota.

Joe Gurrieri, Hydrogeologist

- M.S., University of Connecticut
- USDA Forest Service Scientist
- A hydrogeologist is a person who studies the ways that groundwater (hydro) moves through the soil and rock of the earth (geology). Hydrogeologists evaluate the quantity, quality, reliablity, and sustainability of groundwater.

Sue Eggert, Aquatic Ecologist

- Ph.D., University of Georgia
- USDA Forest Service Scientist
- Aquatic ecologist study how forest and other environmental factors influence the plants, animals, and ecological processes in aquatic ecosystems. This knowledge helps resource managers better manage land and aquatic habitats so they provide clean water for people and wildlife.

Zanethia Barnett, Aquatic Ecologist & Astacologist

- Ph.D., University of Mississippi
- USDA Forest Service Scientist
- An aquatic ecologist studies the interactions between aquatic animals and their environment and an astacologist studies crayfish. I focus on how the changes humans make in aquatic ecosystems and their surrounding watersheds impact aquatic animals, expecially crayfish.

Erika Cohen, Physical Scientist

- M.S., University of Mississippi
- USDA Forest Service Scientist
- A geographic information system (GIS) is a computer system that can capture, store, analyze, manage and display geographic data. A GIS professional uses the computer system to perform spatial analyses on geographic data to answer scientific questions and present the results in maps.
