Development and application of biostatistical and epidemiological methods for analysis of longitudinal health data obtained in support of decision making in a clinical or policy environment. Particularly interested in human development and the epidemiology of mental disorders including dementia. Development of statistical methodology for assessing health effects of preventive interventions and environmental exposures. Development and application of statistical and epidemiological models used in disease screening and prevention. Analysis of statistical problems arising from applying evidence-based medicine in a clinical environment. Understanding statistical issues arising from applying developmental epidemiological models to the course of disease. Assessment of risks, adverse effects, and intervention effects on patients, workers or the general public. Focus on problems in which clinical course is critical, data is limited, uncertainty is complex, potential risk is large, models are primitive, and the biological mechanisms of the disease, exposures and interventions are poorly understood.
