Her methodological research interests include longitudinal analysis, survival analysis, joint modeling of longitudinal and survival data, and analysis on incomplete disease history data. Her collaboration areas include aging, endocrinology, diabetes, and pelvic floor disease in women. Her current work involves developing methods for analyzing longitudinal survey data, specifically adjusting for bias caused by survival-selection and attrition, and using these methods in applications to problems in aging research such as understanding changes in functionality and disease burden in aging process. She has been an investigator on the ACL study since 2011.
