Park is an organizational scholar with an overarching research question, "how can health and social service organizations provide more responsive and effective services?" He is deeply interested in (1) how to ensure user's meaningful representation opportunities in service and policy decision-making processes, and (2) how intra/inter-organizational collaborations and macro-level measures influence organizational behaviors and shape the experience of vulnerable service users. As a scholar using organization as a main unit of analysis, Park's study spans across multiple fields, including but not limited to substance use disorder treatment centers, community-based organizations in South Side Chicago, child and youth serving organizations, homeless-serving regional networks and HIV prevention service providers.
