Study Design and Grant Proposal Development

We help investigators refine objectives into testable hypotheses, choose study designs, develop data analysis plans, and perform power analyses and sample size calculations.

Statistical Data analysis

Consulting services for clinical and translational studies including statistical data analysis, results interpretation, and dissemination of findings.

Qualitative Research Collaboration

We facilitate collaboration with qualitative experts and offer consultation on qualitative study design, data collection, and analysis.

Systematic Review Core

The core provides researchers with tools and resources designed to help conduct systematic reviews for a wide variety of subjects.

Literature Searches

The Health Science Center Libraries (HSCL) at the University of Florida offer specialized expertise in searching and critical appraisal of the literature to researchers developing clinical and translational studies.

Data Management

Manage your study’s data with the technical expertise, secure infrastructure, and compliance controls provided by the RDDC.

Privacy-preserved Medical Data Sharing

Privacy-preserved medical data sharing services can transform sensitive data into data appropriate for collaboration between institutions. The RDDC has established data masking methods that protect privacy while maintaining data utility.
