Primary Responsibilities/Activities:
KathiJo is a Research Ecologist and the Principal Investigator for the Water Quality Component of the Long Term Resource Monitoring (LTRM) element on the Upper Mississippi River System. KathiJo oversees the collection, quality assurance, analysis, and synthesis of water quality data on the Upper Mississippi in cooperation with 4 federal agencies and 5 Midwestern state natural resource agencies.

In addition, KathiJo is broadly interested in understanding the influence of climate and land use change on the function of the Upper Mississippi and other large river ecosystems. She has diverse research experience in aquatic ecosystems from boreal to tropical regions, and is primarily focused on doing research that facilitates better management and conservation of freshwater habitat and water quality.
