Christina Mair is a social epidemiologist and an assistant professor in the Department of Behavioral and Community Health Sciences at the University of Pittsburgh. Her research focuses on the social ecology of substance use, model-based approaches to study drinking behaviors and related problems and population-based analyses of alcohol-related problems such as violence. She is the principal investigator of an NIH NIAAA-funded R01 that uses small scale multi-methods approaches, including local survey and archival data, to assess four specific social mechanisms that may link over-concentrations of off-premise alcohol outlets in neighborhood areas to alcohol-related problems (e.g., violence and heavy drinking). She also leads an NIH project to generate behavioral risk models in an agent-based modeling framework to better understand and intervene to reduce alcohol-related problems in community contexts. In addition to her alcohol-focused research, she studies the spatial and social patterns of opioid use in Pennsylvania.
