The Administrative Team will provide support in three principal areas: 1) administrative, fiscal and scientific oversight; 2) coordination and communication about the Center to maximize its interaction with and impact on external research, engagement, and translation; 3) evaluation of the Center to provide ongoing feedback and quality improvement with respect to all its goals. Because of the inherent complexity of research and engagement around microplastics (MPs) and human health, we have carefully structured an Administrative team and structures to coordinate between two institutions (the University of Rochester and the Rochester Institute of Technology), multidisciplinary researchers, the central role of the Materials and Metrology Core (MMC), and engagement with multiple partners. Our internal coordination will be facilitated by an Internal Steering Committee which will meet monthly, along with quarterly "All Hands" meetings to encourage interaction among all members of the Center, including trainees, staff, and faculty, and monthly meetings of the Microplastics Research Workgroup of Western New York. The Administrative Team supports multi-directional interactions with external stakeholders by facilitating the Lake Ontario MicroPlastics Engagement and Research (LOMPER) group, comprised of organizations with significant roles in management, private sector, or public decisions related to MPs. Core A also manages communications with and annual meetings of our External Advisory Committee, co-hosting an annual Regional Microplastics Research Workshop, and facilitating presentations about Center research with academic audiences. The Administrative Team has dedicated effort to comprehensive formative evaluation and feedback on all aspects of the Center. In addition to standard measures of research progress success, such as publications and presentations, we will monitor use of the MMC, document non- scholarly products (e.g. news media, CEC materials, science briefs), and engagement of Center members in CEC activities. Findings will be reporting on a regular basis to the Internal Steering Committee, LOMPER, and External Advisory Committees to inform future activities.
