Dr. Wang's primary research interests areto understand the fundamental mechanisms of transcription and epigenetic regulation, chromatin remodeling, and DNA repair.  His group takes a multidisciplinary approach, combining structural biology, chemical biology, computational biology, biochemical, and genetic methods, to study key protein complexes involved in these processing pathways. 

A major direction of his laboratory has been to elucidate the mechanisms by which DNA damage is recognized and repaired during transcription. Specifically, his group is focused on the mechanism of the initiation of transcription-coupled DNA repair (TC-NER), which is an important DNA repair pathway that specifically removes DNA lesions in the transcribed genome.  The results will have implications for DNA damage recognition and DNA repair. Moreover, understanding how cell process these DNA lesions will help us to decipher the mechanisms of drug action and resistance and pave the way for rational improvement of novel anticancer drugs.
