Dr. Liu is a population health researcher dedicated to study and address the leading causes of child mortality. She has multidisciplinary background in medicine, maternal and child health, epidemiology, biostatistics, and demography. Her research focuses on applying interdisciplinary quantitative strategies to measure and estimate all-cause and leading cause-specific child mortality, and to investigate jointly their biosocial etiologies. Dr. Liu practices to disseminate evidence on reducing child mortality due to leading causes and advocate to improving child survival. She also teaches introductory and advanced quantitative population health and demographic methods.

Dr. Liu has been investigating methodological and substantive issues to improve the estimation and estimates of levels and causes of child mortality, particularly in settings with inadequate civil registration and vital statistics (CRVS), and has been generating high impact scientific evidence in this area. Relevant to this work, she is also interested in strengthening CRVS in low- and middle-income countries (LMICs). She has worked on quantifying the burden of leading causes of child mortality in LIMICs, such as pneumonia and diarrhea. Recently, Dr. Liu has become increasingly interested in the complex and joint effects of biosocial etiologies of the leading causes of child mortality, e.g. preterm birth. Her research has been and continues to be supported by the Bill and Melinda Gates Foundation, the Canadian Department of Foreign Affairs Trade and Development, the Johns Hopkins University, the National Institute of Health, and the World Health Organization.
