Research Overview

The overall mission of the Biodata Mining and Discovery Section is to assist and to participate in biomedical research with computational and bioinformatics approaches in support of the ultimate research goals of the NIAMS IRP. We are currently providing NGS (next generation sequencing) data analysis related bioinformatics support, focusing mainly on ChIP-Seq and RNA-Seq based research projects. We implement established data analysis approaches and apply them to a wide range of biological and biomedical studies. We also develop new data analysis algorithms and strategies, and conduct research to evaluate emerging methods and techniques in the rapidly evolving field of applied bioinformatics and computational biology.
