RESEARCH SUMMARY

The Chen lab studies DNA topology in the context of chromatin organization and gene expression in human cells, utilizing our strength of developing novel genomic technologies and single-cell assays. We seek to understand how the supercoiling tension of the DNA double helix interact with other chromatin features, contribute to the chromatin environment and gene regulation, as well as the regulatory mechanism and function of DNA supercoiling dynamics and topoisomerase activities during various biological processes. The long-term goal is to apply new scientific discoveries in chromatin biology and new methodologies in single-cell genomics to cancer biology and medicine.
