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 aging policy work includes (1) examining the effects of a LTSS rebalancing initiative; (2) examining age-friendly initiatives on the resilience of older adults to disasters; (3) developing a national blueprint for dementia LTSS; and (4) developing instruments to assess medication reconciliation for post-acute care settings. Her recent environmental health work includes (1) understanding environmental contributions to mental health and substance use disorders; (2) developing a national database of demographic, social, economic, and physical characteristics of neighborhoods and testing how they influence cognitive aging and dementia risk; (3) estimating chemical exposure risks following climate change-related weather events; and (4) clarifying the health and mental health effects of lead exposure and ambient air pollution. Her behavioral health work includes (1) studying the impacts of poor sleep and developing recommendations for the DoD to improve sleep programs and policies in the military; and (2) identifying multi-level 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 designs, qualitative data collection, and advanced statistical analyses including latent variable modeling. She also leads the Climate Change and Health Interest Group for RAND Health. She received her Ph.D. in psychiatric epidemiology from Johns Hopkins Bloomberg School of Public Health.
