Methods Core

The Methods Core provides expertise in research design, statistical analysis, qualitative and mixed-method research, and data management. This core is creating a data repository and unified data architecture to optimize users’ ability to access formative data as well as engage in resource sharing. It supports the Mental Health Disparities Core by managing the technical aspects of and access to the two consent-to-contact databases as well as the Shared Instrument Library.

This core is led by Daniel Feaster, PhD (Core Director), Raymond Balise, PhD, and Joseph De Santis, PhD (Core Co-Directors).
