I am a programme leader at the MRC Laboratory of Molecular Biology.

During my PhD I studied the mechanims of DNA interstrand crosslink repair. I went on to explore the mechanims through which aldehydes damage DNA. I now focus on understanding  how genetic information is faithfully passed from one generation to the next.
