Lu Chen, PhD, is an assistant investigator with Kaiser Permanente Washington Health Research Institute (KPWHRI) who helps to improve medication safety, cancer survivorship, and maternal and child health. Her methodological research focuses on using administrative and electronic medical record (EMR) data from various sources for epidemiologic research.
Dr. Chen has worked with “big data” from national sources, such as the National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER)-Medicare Database. She has also used administrative data from Optum (a large national health insurer), as well as rich EMR data from Kaiser Permanente Washington. By analyzing these real-world data, Dr. Chen studies how common prescription medications affect risk of adverse cancer and pregnancy outcomes.
With various treatment options available for many common conditions, choosing the right treatment according to an individual’s health priorities and health conditions is not easy. The goal of her research is to provide patients and clinicians better information regarding benefits and risks of different treatments to help them make informed decisions.
Dr. Chen joined KPWHRI in September 2016 as a postdoctoral fellow. During her 2-year fellowship, she contributed to several large studies evaluating treatment and other interventions during pregnancy, such as treatment for pregnant women with hypertension and screening for gestational diabetes. She also collaborated with cancer researchers at KPWHRI to study outcomes and patterns associated with opioid use in breast and colon cancer survivors.
Before joining KPWHRI, Dr. Chen completed her PhD in epidemiology at the University of Washington, where she worked with cancer epidemiologists to improve understanding of risk factors, survivorship, and health disparities related to breast cancer. Dr. Chen received her master's in public health from the University of Maryland, where she focused on cultural facilitators and barriers in cancer prevention and survivorship for Asian Americans.

The first Clare Project study asked about values and care preferences. Project leaders are now building on that foundation.
In our learning health system, we discovered that a new screening approach had increased diagnoses without improving overall outcomes. So remarkably, we switched back.

A Kaiser Permanente-led BCSC study is among the largest ever to evaluate adding MRI surveillance for breast cancer survivors.
