Biostatistical methods are taught through the use of a diverse variety of data from public health and biomedicine. Emphasis is given to the appropriate use of statistical software, understanding the statistical content of the public health literature, the limits of statistical inference, and drawing thorough conclusions from results of statistical analysis.

Research Interests

Dr. Rathbun’s research focuses on the analysis of data collected using Ecological Momentary Assessment, a study design in the behavioral sciences that often uses electronic devices (e.g., cell phones) to collect data on salient behavioral events (e.g., smoking a cigarette), and representative samples of participants’ moods and environments in the every-day environments of study participants. He has developed biostatistical methods for fitting mixed-effects versions of recurrent-events models that may be used to describe variation among subjects in how they respond to their moods and environments. His long-term goal is to develop biostatistical methods for delivering adaptive subject-specific behavioral interventions to improve treatment for smoking cessation, dietary compliance, and asthma.
