As Managing Director, Mary is responsible for coordinating and managing CIGLR’s programmatic activities, proposal development, research and administrative budgets, and personnel. Her  primary responsibilities are to (a) lead the implementation of the Engagement, Career Training, and Outreach & Communications (ECO) Program, (b) create and maintain research and administration budget projections, (c) conduct CIGLR hiring and manage personnel research project assignments, (d) oversee research proposal development, and (e) lead the preparation of CIGLR’s annual Performance Progress Report. She has offices at both SNRE and NOAA GLERL to promote interactions with CIGLR and GLERL research scientists, and to help accomplish CIGLR’s goal of supporting NOAA’s mission and strategic goals. Prior to joining CIGLR in 2015, she was a Research Associate at Grand Valley State University’s Annis Water Resources Institute (AWRI) where she worked for 11 years. She is honored to be devoting her career to promoting the health and sustainability of the Great Lakes.
