I conduct research to inform the development, implementation, and evaluation of health policy that impacts reproductive-age women and their families. I am particularly interested in institutional and government policies affecting health care delivery, quality, and outcomes during the perinatal period. I also conduct research on policy impacts among special populations, including working mothers, racial and ethnic minorities, low-income women, and rural populations. My current research examines the measurement and improvement of maternity care quality, with a focus on vulnerable populations and geographic variations.
