Lisa Galloway Evrard, Senior Program Coordinator, has an extensive background in aquatic biology, water quality modeling and monitoring, statistical data analysis, and education. After graduating from Lehigh University with a B.A. in Biology and a M.S. in Ecology from Rutgers University, she worked as an environmental consultant for ten years. Her work as an environmental consultant focused on the development, implementation, and analysis of biological and physicochemical stream assessment and modeling studies, the development of site-specific water quality criteria and modification of permit limits, as well as the preparation of environmental assessments and environmental impact statements. Prior to joining the Water Resources Program in 2002, she was the Assistant Director of the Math & Science Learning Center and the Transfer Student Coordinator for the Faculty of Arts and Sciences Transfer Student Office at Rutgers University for four years. She was instrumental in the implementation of science education outreach programs for students and teachers in grades K-12 at the Math & Science Learning Center. She was also instrumental in developing and providing academic support services for new transfer students to the University, especially those enrolled in math and/or science courses. Her role in the Water Resources Program is to develop and implement Extension water quality and outreach programs, among other watershed management programs. Additionally, Ms. Evrard’s background in water quality monitoring and biological assessments proves to be invaluable in our watershed assessment efforts.
