Vivien Tsu is Clinical Professor of Global Health. She retired from PATH after 37 years working on women and child health issues, including breast and cervical cancer, immunization, maternal health, and evaluation of innovative technologies and approaches to public health problems. Dr. Tsu holds an MA in African History from UC Berkeley, an MPH from UCLA, and a PhD in epidemiology from the UW. She worked in Africa and Asia, as well as in Peru and Ukraine. She spent a year in Zimbabwe as a Fulbright Fellow doing research on maternal health and obstetric complications.

Her work in cervical cancer has spanned more than 25 years, validating new screening methods like visual inspection and HPV testing and practical strategies like screen-and-treat in low-resource settings. She headed a team at PATH that collected ground-breaking data on the feasibility of delivering HPV vaccine to young adolescent girls in low-income countries. She currently serves on Gavi’s Independent Review Committee to evaluate country applications for vaccine support. Her work in breast cancer started in Ukraine, and she led PATH’s project to bring breast health services to the community level in rural Peru.
