Amanda L. Brewster, Ph.D., M.Sc.

Associate Director

Amanda L. Brewster, Ph.D., M.Sc., is an Assistant Professor of Health Policy and Management at the University of California, Berkeley. She is an expert in health care management, with a research agenda focused on innovation to address patients’ social needs in the context of healthcare. Her past work has documented the importance of collaboration among the diverse healthcare and social service organizations that support people with complex needs. Dr. Brewster is currently leading studies on: causes and consequences of partnerships between Community Based Organizations and health care organizations, implementing social needs case management in health care settings, and aligning regional systems for health care, public health, and social services.

Dr. Brewster's research has centered around the integration of health care and social services to address both medical and social determinants of health. Her contributions to science have provided insights to the field in the areas of hospital readmissions, making and embedding change within health care organizations, and older adult care. One example is her dissertation research which investigated quality improvement and organizational learning in the context of hospital efforts to reduce readmissions, and required collaboration among hospitals, outpatient health care providers, and social service providers in the community. Since then, her research has focused on understanding how cross-sector partnerships and innovative collaboration models influence potentially avoidable health care use and spending for older adults. She applies a range of methods to understand these issues including qualitative and mixed-methods, organizational network analysis, and longitudinal analyses leveraging large survey-based and claims-based data sets.
