This informal discussion session provides an opportunity for STAR grantees and staff of EPA Program Offices, Labs, and Centers to explore opportunities to further advance the research topics presented. The group will choose the topics to be discussed; preliminary suggestions include:  (1) ways to share data, ideas, or modeling methods, and (2) ways to synthesize and communicate research results. To start off the discussion, we will have three speakers give brief remarks (i.e., 5 – 7 minutes):
Rochelle Araujo, Ph.D., U.S. EPA, NERL, ADE; Charles Noss, Ph.D., U.S. EPA, ORD; and Noha Gaber, Ph.D., U.S. EPA, NCER
4:00 – 4:10 p.m. Closing Remarks
Bernice Smith, Ph.D., Global Change (Ecosystems Research) Program Manager, U.S. EPA, NCER
