The Joung Laboratory develops technologies for genome engineering using artificial “designer” DNA-binding domains. We utilize engineered zinc finger, transcription activator-like effector (TALE), andRNA-guided CRISPR/Cas-based systems to direct specific genomic alterations in living cells and organisms. In addition to developing and optimizing these technologies, we are exploring their applications for biological research and gene therapy.

Dr. Joung’s research interests include understanding how Cys2His2 zinc fingers, the most common domain encoded in the human genome, mediate specific protein-DNA and protein-protein interactions. In addition, Dr. Joung’s lab uses a combination of directed randomization and bacterial cell-based selection methods to engineer artificial “designer” zinc finger domains with desired DNA-binding specificities. The ability to direct functional domains (e.g.—transcriptional regulatory or endonuclease domains) to specific genomic loci using these customized DNA-binding domains will have important applications as tools for biological research and as potential therapeutics for molecular medicine and gene therapy.
