Research Interests

DNA repair, mutagenesis, cancer, and Cas9 genome editing

Research Summary

We are investigating how DNA damage is formed and repaired in chromatin on a genome-wide scale, and how damage formation and repair influences subsequent mutagenesis. Our focus has been on UV-induced DNA damage, which is primarily repaired by nucleotide excision repair (NER) pathway. We are also investigating how nucleosome positioning and histone modifications regulate the repair of DNA base lesions throughout the genome. To advance these studies, we have developed novel genomic tools to map DNA lesions at single-nucleotide resolution throughout the yeast and human genomes. We have also been investigating how chromatin impacts CRISPR-Cas9 genome editing.
