Biostatistics


Director: Soledad Fernandez, PhD
Associate Director:  Kevin Coombes, PhD

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.
