Chuan Zhou, PhD

Academic Title: Research Associate Professor

Research Center: Center for Child Health, Behavior and Development

"In this information age when huge amounts of data are being collected constantly at personal and group levels through social media, digital devices and electronic records, it is crucial to tell good data from bad data, to separate true signals from noises, to tell truth from lies, and understand the implications and consequences of the knowledge we gain from analyzing such big data. Clinical research is no exception. As a biostatistician, my passion is analyzing and making sense of data, and ensuring our clinical studies are valid, efficient and reproducible."

  • Chuan Zhou received his PhD in biostatistics from University of Washington, School of Public Health, Department of Biostatistics. After completing his post-doctoral training, he joined the faculty of Biostatistics Department at Vanderbilt, Nashville. In 2008 he moved back to Seattle and joined Pediatrics at University of Washington and Center for Child Health, Behavior, and Development at Seattle Childrens Research Institute as a research associate professor. Since joining the Research Institute, he has conducted analyses and provided statistical guidance for a wide range of clinical and health services research projects, with focus on 1) childhood obesity, home food environment and physical activity; 2) child and adolescent mental health; 3) cerebral palsy and disability; 4) environmental chemical exposure during pregnancy; 5) impact of screen time and media exposure on infant and toddler cognitive and social development, to name a few. His own statistical research interests include Bayesian statistics, high performance statistical computing, multilevel modeling, longitudinal data analysis, causal inference, and missing data methods.

Research Description

Dr. Zhou's research focuses on myriad issues, notably 1) How to use accelerometers and smart watches to improve children?s physical activity in day care setting; 2) How the Pediatric Respiratory Illness Measurement System performs among pediatric patients with asthma, bronchiolitis, croup, community acquired pneumonia, and acute pulmonary exacerbation of cystic fibrosis; 3) Developing and evaluating the effectiveness of internet-based communication skills training for reducing antibiotic prescribing for bacterial acute respiratory infections, while maintaining or improving patient satisfaction; and 4) Developing and examining novel strategies to improve students? physical activity in under-served school districts in Houston area and Seattle area.
