The Biostatistics Shared Resource (BSR) provides expertise in the biostatistical design and analysis of clinical, basic and population-based research.

BSR services enable OSUCCC – James researchers to collaborate on all aspects of experimental design; grant proposal development; data management and statistical analysis of clinical, epidemiological, public-health and laboratory research data; and manuscript preparation.

BSR assistance in proposal preparation has resulted in funded biostatistics support for new and renewed programmatic grants and a large number of R awards. BSR members obtain grant funding predominantly through collaboration with OSUCCC investigators and most have developed long-term collaborative relationships.

Please contact us at the Center for Biostatistics.


The BSR is staffed by members of Ohio State’s Center for Biostatistics, the Division of Biostatistics in the College of Public Health and the Division of Human Genetics in the College of Medicine.
