It advances this thesis through three research streams: data-centric AI systems across the application domains of public health and personalized medicine, and foundational data science for AI systems. Across these streams, the dissertation introduces new methodologies that integrate prediction, optimization, and action in the presence of delayed reporting, incomplete observations, local data limitations, and distributional instability. Collectively, this work argues that the operationalization of AI is fundamentally a data-centric design problem.\u003C\/p\u003E","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003EOperationalization of AI Systems Through Data-Centric Design\u003C\/p\u003E","format":"limited_html"}],"field_summary_sentence":[{"value":"Operationalization of AI Systems Through Data-Centric Design"}],"uid":"27707","created_gmt":"2026-04-08 15:35:52","changed_gmt":"2026-04-08 15:36:30","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2026-04-20T11:30:00-04:00","event_time_end":"2026-04-20T13:00:00-04:00","event_time_end_last":"2026-04-20T13:00:00-04:00","gmt_time_start":"2026-04-20 15:30:00","gmt_time_end":"2026-04-20 17:00:00","gmt_time_end_last":"2026-04-20 17:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Groseclose 304 ","extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"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":""}}}
