Research Interests

My laboratory studies the molecular basis of cancer therapy. Our goal is to determine how p53 and other mediators of the DNA damage response are activated are activated by therapeutic agents, and to understand how these pathways ultimately control cell growth and death, and mediate tumor suppression.
