Research Interests

Methodology: Evaluating and explaining individual variation in health outcomes and health-related quality of life. Evaluating the effectiveness of health-related interventions, particularly clinical intervention. Contextual effects: how characteristics of the person, social and physical environments, and systems interact to affect health. Applying statistical models to health data, including generalized, multilevel, longitudinal, and latent variable models. Obesity, child obesity, physical activity, exercise, orthopedic surgery, health and wellness, quality of life.
