个人简介
B.A. in Chemistry, Middlebury College (Advisor: Sunhee Choi)
Ph.D. in Chemistry, Caltech (Advisor: Jacqueline K. Barton)
Postdoctoral Fellow in Biological Engineering, MIT (Advisor: John M. Essigmann)
研究领域
The research in my laboratory aims to understand the biological consequences of DNA damage. Using the tools of chemistry and biology we probe the effects of DNA modification at the molecular level. We are particularly interested in the role of oxidative DNA damage and its contributions to cancer and neurological disorders such as Huntington's disease.
