Biostatistics Services

The BBSR biostatisticians collaborate on developing protocols for clinical trials and research proposals for laboratory-based investigations and epidemiologic studies; perform statistical analyses; interpret study results; and co-author presentations and publications. In addition to developing investigator-initiated clinical trials and new research studies, BBSR biostatisticians serve as standing voting members on the Medical Protocol Review and Monitoring Committee (MPRMC), Population Sciences Protocol Review and Monitoring Committee (PSPRMC), and the Data and Safety Monitoring Committee (DSMC). BBSR biostatisticians routinely participate in various Cancer Center forums, such as meetings of the research programs and the Site Disease Groups, and often assist Clinical Research Services (CRS) and the Informatics Applications Management group in the implementation of various projects.
