Description of Research Expertise

Dr. Hubbard's research focuses on development and application of statistical methodology for studies using observational data from community medical practice. This work encompasses evaluation of screening and diagnostic test performance, methods for comparative effectiveness studies, and health services research. A wealth of data on healthcare utilization, performance, and outcomes are available from electronic medical records. However, the complex observation scheme giving rise to these data necessitates careful study design and analysis to ensure that inference is valid. Dr. Hubbard’s methodological research emphasizes development of statistical tools for such inference and has been applied to studies of cancer screening, aging and dementia, pharmacoepidemiology, women’s health, and behavioral health.
