Biostatistics & Bioinformatics Shared Resource Facility (BB SRF)

BB SRF Overview

The mission of the Biostatistics and Bioinformatics Shared Resource Facility (BB SRF) is to apply statistical principles to ensure rigor and enhance the execution of scientific research through a team science model of collaboration with MCC investigators. To this end, our primary goal is to provide centralized, cutting-edge and accessible expertise in biostatistics and bioinformatics to support all phases of cancer studies from study development, implementation, and post-study analyses.

The BB SRF is a cancer center-managed shared resource and comprises of highly experienced personnel with diverse skill sets. We received an Exceptional rating from the NCI’s last review in 2018 and continue to aim to provide value-added to support the mission of the Markey Cancer Center at the University of Kentucky.

Specific Aims

  1. Provide statistical expertise and consultation in study design, study conduct and analysis across the spectrum of projects from MCC Research Programs.
  2. Provide high-quality bioinformatics expertise focused on study design and data analysis across the spectrum of projects from MCC Research Programs.
  3. Enhance MCC research through a team science model along with utilization of unique processes for interfacing across MCC Shared Resources.

To ensure that the BB SRF supports high-quality research, the top three priority areas are: 1) investigators with peer-reviewed funded studies; 2) investigators with non-peer-reviewed funded studies and applying for peer-reviewed grants with proposed BB SRF funding; and 3) investigators conducting MCC pilot studies and IITs.

Consultation and support for grant applications and clinical trial development are provided free of charge. BB SRF also provides limited preliminary data analysis to formulate new hypotheses for proposals to be submitted for funding. More extensive support should provide funding of BB SRF effort on individual grants.
