Primary Responsibilities/Activities:
Jeff is the Science Director for the Long Term Resource Monitoring Branch at UMESC.  In this role, Jeff also acts as the Science Director for the Long Term Resource Monitoring element of the US Army Corp of Engineer’s Upper Mississippi River Research Program.  He works with federal and state partners including the U.S. Army Corps of Engineers, US Fish and Wildlife Service and the 5 UMRS states (Minnesota, Wisconsin, Iowa, Illinois, and Missouri) to coordinate the ongoing, management-relevant research being conducted on the UMRS. He also obtains funds for and conducts additional ecological research on the UMRS.
