Data Management and Statistics Core

Goals and Activities:

  • Provide coordinated and integrated data management capabilities for the ADRC across the Duke/UNC ADRC allowing easy access, tracking, and reporting capabilities for all of the cores.
  • Provide datasets to the National Alzheimer’s Disease Coordinating Center (NACC) and to other collaborative efforts in Alzheimer’s disease discovery and prevention.
  • Provide statistical expertise, consultation and collaboration for data analysis, study design, statistical power calculations, sampling strategies, and statistical prediction or modelling capabilities for the AD grants, projects, and pilots undertaken by the Center’s faculty, as well as for its cores and development projects.
  • Provide bioinformatics consultation to the Center cores and Duke/UNC scientists for management, integration and analysis of large datasets (omic, neuroimaging).
  • Develop innovative statistical and bioinformatics methodologies to meet the needs of the Center.
  • Provide educational opportunities and mentoring of investigators, trainees and junior faculty in collaboration with the Research Education Component on statistical and bioinformatics methodologies for Alzheimer’s disease research.DMS Core data flow diagram
