Welcome to the Chen Lab

Our laboratory is interested in the structure and function of molecular complexes that control cell signaling and gene expression. We use a multi-disciplinary approach that combines structural biology, chemical biology, biochemistry/cell biology, and computational biology/bioinformatics to study the molecular basis of signal transduction and transcription regulation.
