About the CRDC


The NCI Cancer Research Data Commons (CRDC) is a secure, cloud-based data science infrastructure that accelerates cancer research by facilitating data submission, sharing, access, interoperability, and cost-effective analysis at scale.

The CRDC makes more than 9.4 petabytes of data accessible from hundreds of NCI-funded programs and studies, as well as data from select external cancer research programs. Additionally, the CRDC offers cloud computation, analytics, and visualization tools that enable the research community to create more powerful ways to make discoveries that accelerate progress to prevent, diagnose, and treat cancer.

The CRDC includes:

  • Data Commons that collect and manage NCI-funded and approved research data as well as data from select external cancer research programs
  • Cloud Resources that provide secure workspaces and access to thousands of analytical tools to be tailored or used as is
  • An underlying infrastructure with a continuously evolving common data model, as well as defined data standards and services that ensure secure storage, search, and data aggregation across multi-modal research data 

Meet the Team

The CRDC is integral to the mission of the Data Ecosystem Branch, one of three branches included in the Information and Data Sciences (IDS) Program at the Center for Biomedical Informatics & Information Technology (CBIIT), NCI. Each of the CRDC components is led by a data science and/or cancer research professional. The CRDC team collectively represents a broad range of expertise, and includes collaborative leaders from various NCI Divisions, Centers and Programs.
