Biography

Dr. Coffman’s research focuses on improving methods for causal inference, specifically for continuous treatments and mediation. She is currently the Principal Investigator of an R01 project sponsored by the National Cancer Institute to develop time-varying mediation analysis and she is an investigator on an R01 project funded by the National Institute on Drug Abuse to develop software tools for estimating causal effects using propensity score weighting. She develops and applies methods for analyzing data from wearable and mobile devices and ecological momentary assessments to inform the development of individualized adaptive interventions and to examine dynamic causal effects. Her substantive research has primarily fallen into three areas: substance abuse prevention and treatment, smoking cessation, and obesity prevention. She received her Ph.D. in Quantitative Psychology from the University of North Carolina, Chapel Hill.
