NHLBI BioData Catalyst® (BDC)
BDC brings together rich longitudinal, phenotypic, and genomic data, so researchers can discover, combine, and analyze data at scale without managing complex infrastructure.
Why BDC?
Access well-characterized data from longstanding NHLBI studies and programs.
Bring together information across studies, cohorts, phenotypes, and genomic resources to ask questions beyond a single dataset.
Use secure, scalable cloud environments and reusable analytical resources alongside the data.
Data in BDC
Long-running cohort and observational studies with repeated measures over time
Detailed health, behavioral, environmental, and clinical characterization
Whole-genome sequencing and complementary molecular data
Imaging, sleep, physiological, and disease-specific research data
Connect data across studies and data types to ask questions that extend beyond a single dataset.
A growing resource with broad coverage and deep scientific value.
BDC helps researchers move from finding a relevant study to asking questions across multiple datasets. Explore NHLBI data, identify studies or cohorts that fit your research question, and move directly into secure cloud environments where data can be analyzed individually or together.
BDC supports the research process from data discovery and access through analysis, collaboration, reproducibility, and publication.
