Biostatistics Shared Resource (BSSR)

The Biostatistics Shared Resource works collaboratively with cancer research investigators in providing analyses, computational methods, models and algorithms. In this way, it helps researchers from concept development to the publication of results and design of subsequent research.

The resource’s involvement substantially contributes to advancing research and spans numerous cancer center project areas, including basic, translational and community-engaged research.

Biostatistics Shared ResourceLocation and Hours of Operation

Cancer center drop-in site. Staff biostatisticians assist cancer center members 10 a.m. to noon Wednesdays and 1 to 3 p.m. Fridays in Clinical Trials Office Room 3236 (enter through 3233).

Health Research Center, MCW campus. The shared resource is located in the Health Research Center. Every cancer center member has access to the shared resource online and via telephone and email.


Biostatisticians specializing in cancer research provide the following:

  • Study designs for clinical trials, survey sampling, laboratory experiments, observational studies
  • Formulation of statistical hypotheses
  • Recommendations and planning of statistical methodology
  • Protocol development
  • Randomization
  • Data monitoring
  • Modeling, analysis and interpretation
  • Manuscript preparation


The BSSR has a network of servers and workstations in a secure Linux operating system environment that are equipped with a variety of statistical software. This system is used extensively for data preparation and analysis by BSSR members. In particular, the system contains servers for parallel CPU computing and massively parallel GPU computing. Software includes compilers for C/C++/Fortran, as well as the statistical platforms R and SAS. There are seven Linux CPU servers with a capacity to run 272 processes in parallel simultaneously and one Linux server capable of running processes on 7000 GPU cores simultaneously. The system is designed with automatic nightly backup of all files. Data safety is also enhanced by using redundancy via a RAID system and security is ensured via Linux password protection and encryption.
