Research Interests
Our lab is focused on understanding the fundamental principles of selective gene expression in mammalian cells. We use early embryonic stem cells and cancer cells as our model system, combine genomics, proteomics, bioinformatics, genome editing, imaging and biochemistry techniques. Specific research direction includes:
1) Investigating the molecular mechanisms for the novel functions of RNA polymerase subunits.
2) Understanding the roles of RNA polymerase subunits in human brain diseases.
3) Screening RNA aptamers for RNA polymerase subunits.
