Regina Shih is a senior behavioral and social scientist at the RAND Corporation. She currently has three primary research areas: aging policy, environmental health, and behavioral health. Her recent environmental health work examines environmental contributions to the development and trajectory of mental health and substance use disorders. Projects include developing a national database of neighborhood environment indicators to examine whether demographic, social, economic, and physical characteristics of neighborhoods influence cognitive aging and dementia risk; estimating chemical exposure risks following climate change-related weather events; and understanding the health and mental health effects of lead exposure and ambient air pollution. Her aging policy work includes examining age-friendly initiatives on the resilience of older adults to disasters, developing a national blueprint for dementia long-term services and supports, and recommending instruments to assess medication reconciliation across all U.S. post-acute care settings. Her mental health work includes studying mental and physical health impacts of poor sleep and developing recommendations for the DoD to improve sleep programs and policies in the military; and identifying individual, family, peer, and neighborhood risk and protective factors for adolescent substance use and risk behaviors. Shih is skilled at leading sophisticated mixed-methods studies that incorporate large epidemiological study design, qualitative data collection, and advanced statistical analyses including latent variable modeling.
Before joining RAND, Shih completed a post-doctoral fellowship in children's environmental health at NICHD while working on the National Children's Study. She holds a Ph.D. in psychiatric epidemiology from the Johns Hopkins Bloomberg School of Public Health.
