Congratulations to Ruth Etzioni on her election to the Washington State Academy of Sciences.

Etzioni is an affiliate professor of biostatistics in the University of Washington School of Public Health and a professor in the Public Health Sciences Division at Fred Hutch. She was elected for “pioneering statistical models that transformed cancer early detection and screening policy, reshaping national and global guidelines and advancing equitable public health decision‑making, and for exceptional leadership, cross‑disciplinary collaboration, and mentorship, influencing generations of scientists.”

Vaccine hesitancy rose significantly during the COVID-19 pandemic and remains a growing challenge today. Understanding what drives concerns about vaccines remains a crucial public health goal, as falling vaccination rates have led to the recent resurgence of preventable diseases.

UW Biostatistics faculty member Robin Mejia led a team that analyzed more than 310,000 responses from the U.S. Covid-19 Trends & Impact Survey (CTIS) to model how the different reasons selected by an individual might be related. By grouping an individual’s responses into patterns, researchers identified two different types of hesitancy: people with health-related concerns and people who distrust the government and vaccines. Mejia and her team also looked at responses by race, and how hesitancy rates changed as vaccine rollout progressed.

Congratulations to UW Biostatistics faculty member Ting Ye on her promotion to associate professor with tenure, effective July 1, 2026.

Ye develops statistical methods for clinical trials and causal inference, and most recently multimodal AI for biomedical science. At her TREND Lab, she pairs AI with causal inference to find what changes outcomes, not what merely predicts them, and tailors AI advances to clinical development, accelerating timelines and improving success rates without relaxing rigor. As evidence generation multiplies in the AI era, she is also building the statistical infrastructure that next-generation trials will require, including platform trials and other complex innovative designs.
