Peter O'Neill

Emeritus Professor

Research Summary

My interests over the years have focussed on the chemistry and biochemical pathways involved in the repair of radiation-induced DNA damage and more recently have focussed on clustered DNA damage.


Professor O’Neill was the Course Director of the MSc in Radiation Biology until 2016 and Deputy Director of the Oxford Institute for Radiation Oncology within the Department of Oncology until 2017.

Following post-doctoral positions first at the Max-Planck-Institut für Strahlenchemie in Mülheim, Germany, and then at the Institute of Cancer Research in Sutton, UK, he spent 23 years carrying out research at the MRC Radiation and Genome Stability Unit (formerly Radiobiology Unit) in Harwell, Oxfordshire. He came to Oxford to lead the DNA Damage Group in 2005 until his retirement in 2017. 

He is Associate Editor of the International Journal of Radiation Biology and of Radiation Research and has over 235 peer-reviewed publications. He provides consultancy and advice to several international organisations including NASA and EU funded MELODI Consortium.  He was President of the Radiation Research Society of USA in 2010 and serves on several international committees relating to radiation. He is a Fellow of the Royal Society of Chemistry and was awarded the Failla medal and the Weiss medal as an outstanding member of the scientific community in recognition of a history of significant contributions to radiation research.
