Gayle S. Bieler is a senior statistician and Director of RTI’s Center for Data Science. In this role, she leads a group of data scientists, statisticians, and predictive modelers who collaborate with RTI researchers in expanding our internal and external capabilities in data science—big data methods, data visualization, and predictive analytics. The focus of the group is to use data science to solve problems and inform decision-making across all of RTI's research domains for projects in government, foundation, and commercial spaces.  

As a statistician by training, Gayle is also experienced in statistical analysis of complex data from designed experiments (clinical and toxicology studies), observational studies (sample surveys, epidemiology studies), and most aspects of commercial software development. She has also made major contributions to the direction, development, and marketing of SUDAAN, RTI’s commercial software package for analyzing data from complex sample surveys and experimental studies involving cluster-correlated and longitudinal responses. Gayle holds a Master’s degree in statistics from Boston University.
