Research Interests & Collaborations
I am interested in behavioral health risk factors, namely, diet, substance use, stress, and physical activity (both exercise and reducing sedentary behavior), the causal antecedents of engagement in these behaviors, and the causal effects of these behaviors on health outcomes. My goal is to examine dynamic causal processes of health behavior change and maintenance. Ultimately, I hope to inform the development of individualized ecological momentary interventions to promote engagement in and maintenance of healthy behaviors. Achieving this goal requires high-resolution data on multiple time scales of observation and at multiple levels of analysis (e.g., environmental, social, behavioral, physiological, genetic).
I am currently developing and applying methods for analyzing data from biosensors, ecological momentary assessments, and genomics. My aim is to identify momentary risk states for physical inactivity and stress. I work on extending statistical learning/data mining methods to estimate propensity scores in the mediation context. I am developing a method to estimate multi-level propensity scores for continuous exposures. Finally, I collaborate on a project using propensity score methods to model peer influence and selection effects in social networks.
