Chongzhi Di is an Adjunct Professor in the Biostatistics Program at the Fred Hutchinson Cancer Research Center (Fred Hutch), part of the Public Health Sciences Division. He is also a member of the Translational Data Science Integrated Research Center (TDS IRC) at Fred Hutch. His research focuses on developing statistical methods for analyzing functional and longitudinal data, with applications in mobile health, physical activity epidemiology, and wearable device studies.
Dr. Di holds a PhD in Biostatistics from Johns Hopkins University (2009) and a BSc in Applied Mathematics from Peking University (2003).
Research Interests: Functional data analysis, longitudinal studies, latent variable models, semi-parametric regression, mobile health interventions, and accelerometer-measured physical activity metrics. He collaborates on studies addressing schizophrenia, cardiovascular disease, sleep disorders, and psychiatric conditions, leveraging wearable technology and smartphone apps for health monitoring and intervention.
Key Contributions: Pioneered novel statistical tools for quantifying dose-response relationships between activity patterns and health outcomes, particularly through ancillary studies of the Women’s Health Initiative. His work includes developing metrics for physical activity intensity, frequency, and duration, as well as compositional analysis frameworks. A recent milestone study focused on tailoring physical activity tracking for older adults using mobile health technologies.
