  • Radiation damage in biological systems

I am currently completing the final year of my PhD on radiation damage to DNA. In particular I have been working on the low energy secondary effects of electrons interacting with DNA components. Our recently published paper [M Smyth and J.J Kohanoff, Phys. Rev. Lett., 106, 238108 (2011)] has attempted to bridge the gap between the gas phase calculations and in vivo DNA. We believe that it is vital to include a thermally fluctuating and fully solvated environment in order to realistically model DNA strand breaks.

DNA damage caused by irradiation has been studied for many decades. Motivations include assessing the dangers posed by radiation, and understanding how to improve its efficiency in combating cancer. Surprisingly, low energy electrons (3eV) play an important role in this damage. My work aims to understand the behaviour of DNA components in the condensed phase, due to the presence of such electrons.
