CAREER DEVELOPMENT AND TRAINING CORE: PROJECT SUMMARY/ABSTRACT The NY-CHAMP Career Development and Training Core (CDTC) will serve as a local and regional scientific career development hub that 1) offers resources and activities to foster cross-disciplinary, cross-sector collaboration and 2) sets the stage for a highly diverse, highly collaborative network of scientists poised to advance innovative, community-centered, anti-racist, multi-level solutions for maternal health equity. The CDTC will draw on the rich institutional resources of Columbia and Cornell University Medical Centers and synergize with the vast knowledge and assets of our strong community, governmental, hospital, and academic partners to transform the pipeline of maternal health scientists to be interdisciplinary in approach and committed to community-centered, health equity, and anti-racism research. In Aim 1, we will transform the maternal health research culture to create a pipeline of diverse scholars who are committed to community engagement and expert in interdisciplinary, multi-sector research partnerships. In Aim 2, we will operate as a hub for maternal- health-focused training opportunities and resources in structural racism, cultural humility, racial allyship, and diversity, equity, inclusion, and justice. In Aim 3, we will engage early-stage investigator (ESI) NY-CHAMP Scholars in hands-on training in intervention science that is community-led, anti-racist, and interdisciplinary via a collaborative, to-be-designed demonstration project. Our training philosophy values co-creation and co- implementation of methods and interventions informed by, respectful of, and responsive to the needs of the diverse communities we serve. The CDTC will contribute to the overall goals of the NY-CHAMP Center of Excellence by grounding scholars in the culture and structural change that is required to foster innovative new science and sustained community partnerships for research impact on maternal heath equity from the next generation of researchers.
