CHEAR Data Center

NIEHS has established the Children’s Health Exposure Analysis Resource (CHEAR) infrastructure to provide the extramural research community access to laboratory and statistical analyses aimed at adding or expanding the inclusion of environmental exposures in their research. CHEAR is composed of a Coordinating Center, a Lab Network and a Data Center tasked to provide researchers access to comprehensive exposure assessment for NIH funded studies of children’s health. The Center for Data Science (“Data Center”) at the Icahn School of Medicine at Mount Sinai goals are to catalyze new scientific insight from the co­location, integration and advanced statistical and data science analysis of multimodal data sets. We will provide:

  • A data repository for storing epidemiologic and biomarker data for an approved CHEAR research study
  • Statistical methods development
  • Publicly available deidentified datasets downloadable for external users
  • A publicly accessible CHEAR ontology that provides a common vocabulary with unambiguous definitions of concepts and variables across studies to allow for pooling of studies
