Yet as digital platforms increasingly shape the modern public health information ecosystem, taking a community-based approach to working with these platform technologies introduces challenges of working across levels of scale.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EMy dissertation proposal presents my work across five interlinked statewide community-engaged research coalitions, supporting community-based communicators to critically investigate and leverage digital platforms to promote public health. Using qualitative and design research methods alongside system development, my research examines the work of two collaborating groups of intermediary actors: the community-based health communicators, and the researchers including myself in these large coalitions. I consider how we navigate various boundaries of institutions, technologies,\u0026nbsp;cultures, disciplines, and timescales to design tools and strategies around digital platforms, as well as to design our own structures and processes for collaboration.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EMy completed work includes two studies investigating the use of social media platforms and analytics by community-based health communicators, including (1) young adult peer messengers and (2) community health workers. Turning the lens inwards, (3) my third completed study unpacks our research team\u2019s experiences of technological and institutional seamfulness in developing and operating a tailored health messaging system. My proposed work includes (4) participatory engagement with community-based health coaches to design and develop an LLM-based AI system to support their training and work; and (5) an autoethnographic reflection of my own participation in and shaping of these sociotechnical research coalitions through evolving digital health threats. Through this research, I contribute towards extending digital health to the level of digital platforms and communities, expanding our narratives of and approaches to pluralistic community-engaged research at broader scales, and ultimately raising the platform of those who work to advance community health.\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EPlatforming Digital Community Health\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Platforming Digital Community Health"}],"uid":"27707","created_gmt":"2025-11-11 17:29:17","changed_gmt":"2025-11-11 17:29:17","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2025-11-18T10:30:00-05:00","event_time_end":"2025-11-18T12:30:00-05:00","event_time_end_last":"2025-11-18T12:30:00-05:00","gmt_time_start":"2025-11-18 15:30:00","gmt_time_end":"2025-11-18 17:30:00","gmt_time_end_last":"2025-11-18 17:30:00","rrule":null,"timezone":"America\/New_York"},"location":"TSRB 217A","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"102851","name":"Phd proposal"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
