Biography
Weiwei Zhu, MS, joined Kaiser Permanente Washington Health Research Institute's Biostatistics Unit in 2009. She works closely with Affiliate Investigator Diana Miglioretti, PhD, to design studies, manage data, and conduct statistical analyses for the Breast Cancer Surveillance Consortium (BCSC) — the National Cancer Institute’s 7-site network of mammography researchers. She has been a key member of the BCSC Statistical Coordinating Center for over 10 years. Her work studying breast screening benefits and risks played an essential role in an American Cancer Society screening guideline change in 2015.
Weiwei’s current other studies include testing the effects of sitting reduction on cardiometabolic health outcomes through a large randomized trial in older adults, studying a sedentary behavior reduction and physical activity promotion intervention for the older Latino/Hispanic community, and examining the association of the 24-hour activity cycle with cognition and physical function in older adults with Senior Investigator Dori Rosenberg, PhD, MPH. Weiwei has also collaborated on research to quantify the serious risks of misuse, abuse, and addiction associated with long-term opioid use. This multi-site study used electronic health record data and survey interviews to provide estimates of long-term opioid use risks in 2 cohorts.
After beginning her medical research career as an intern at the University of Texas MD Anderson Cancer Center in 2007, Weiwei served as a biostatistician at the Moffitt Cancer Center and Research Institute in Florida.
