Research Focus

My research focuses on the regulation of transcription in mammalian cells and, in particular, the roles of transcription factors in DNA repair and DNA damage responses. We combine a vast array of molecular biology and functional genomic approaches together with tissue culture and mouse models to investigate how alterations in DNA repair and DNA damage responses contribute to the initiation and progression of cancer. It is generally accepted that defects in DNA repair, whether transient or permanent, contribute to tumor development and progression. Yet, to replicate their DNA and proliferate, cancer cells need DNA repair mechanisms, perhaps even more than do normal cells. We study how defects in DNA repair can contribute to tumor initiation and how certain cancer cells become dependent on specific DNA repair pathways. The goal of our work is to use the acquired knowledge to exploit the sensitivity of cancer cells to specific radiotherapeutic and chemotherapeutic treatments.
