Featured Division

Biostatistics Research

Our biostatisticians provide expert guidance on working with real-world clinical data to investigators in all of our scientific divisions.

Investigators with the Division of Biostatistics Research collaborate closely with scientists from the department’s other scientific divisions, as well as physician researchers at medical centers across Kaiser Permanente Southern California. They provide expertise and guidance on study design, power and sample size calculations, data management, data analysis and interpretation, and statistical methodology.

Investigators from the division have expertise in study design and data analysis for observational studies and clinical trials to address study questions. Their expertise spans standard and modern methods that deal with complex and big data for population and causal inferences as well as disease prediction.

Each division has at least one dedicated collaborative biostatistician research scientist assigned to provide statistical guidance on its research studies. In addition, one of the collaborative biostatistician researcher scientists leads the Regional Research Statistical Support team, which supports medical center-based researchers.
