Data Mining at the National Center for Toxicological Research

NCTR Data Mining Work

National Center for Toxicological Research (NCTR) conducts full range of product safety and translational safety studies in support of FDA’s product portfolio including foods, cosmetics, dietary supplements, human and animal drugs, tobacco and devices. Text mining and data mining are mostly pursued in the Division of Bioinformatics and Biostatistics, and are designed to align with FDA Product Center needs, both current and prospective.

Current Initiatives
  • Next-generation sequencing (NGS) quality control; application of RNA-seq; quality control metrics for improving reproducibility of SNPs called from DNA-seq data.
  • Development of qualitative and quantitative prediction models for different toxicological endpoints.
  • Data analysis and data mining for pathogen detection and characterization.
  • Safety signal detection and analysis in the FDA’s adverse event reporting systems.
  • Data mining on FAERS and Electronic Medical Records  to detect drug-induced cardiac disorders and drug associations using big data analysis.
