Tiffany L. Lemon is an epidemiologist and assistant professor of health services research at the Arizona State University's College of Health Solutions and Center for Health Information and Research. Her research identifies and quantifies the impacts of sociopolitical factors that influence health care access and produce health inequities among marginalized populations. Lemon’s current work leverages longitudinal data and causal inference methodologies to estimate the effects of health insurance coverage on patient outcomes including health care utilization, HIV disease progression, and health-related quality of life. Using the target trial framework, Lemon emulates hypothetical randomized trials to reduce the impact of biases and to assess the comparative effectiveness of health access strategies when resources or support for research in real-world settings are lacking. Prior to her current role, Lemon earned a bachelor's degree in biochemistry at Louisiana State University as a LA-STEM Research Scholar, a master's of public health degree in global epidemiology from Emory University’s Rollins School of Public Health, a doctorate in population health sciences from the Harvard T.H. Chan School of Public Health, and completed a postdoctoral research fellowship as a T32 trainee at the Center for Global Health and Massachusetts General Hospital.
