SenNet CODCC Supplement Abstract The purpose of the Supplement is to further the CODCC Administrative Core (Sub-Section C: Administrative Core: Including Consortium Coordination & Outreach) in three areas: 1. onboarding each of ten additional murine awards and integrating them into consortium, 2. developing and executing a comprehensive, nationwide, underrepresented scientific internship award program in cellular senescence based on the NIH criteria, and 3. expanding opportunities to gather, in person, the consortium and others focused on related technologies and platforms. Given the large expanding of consortium awards focused on murine data, additional support and coordination will be required to handle the rapid growth in the development of the broader overall SenNet eco-system. This includes coordination with other single cell platforms at a larger scale to best serve the expanded SenNet Consortium adding substantive murine focus, and the broader research community. Internships will allow learning valuable new skills across the scientific research spectrum and gain experience in an educational lab environment. During the internship program, students will conduct cutting-edge research, greatly expanding their knowledge of biology and data analysis. Students will develop a variety of skills throughout the summer. CODCC received significant input in year one in working groups and from NIH regarding the consortium’s interest in meeting in-person more often, and particularly in focused areas among awards and outside parties with shared interest. These interests cover both biology laboratory technologies and associated computational pipelines. Following through on this will require additional management of meetings, workshop/panels/working groups, & data-thons and hackathons. To achieve these aims will also require expansion of communication and engagement to other common fund consortia, among the vendor ecosystem, and to the public interested in the science of Cellular Senescence and its human impact.
