Research Summary

Deciphering how efficient and faithful replication of the human genome is achieved within the highly-complex, dynamic, and reactive environment of the nucleus. Identifying pathways for genomic instability in humans, identifying novel oncogenic drug targets, developing better chemotherapeutic treatments for human cancers caused by genomic instability.
