Other clinical interests

  • Dr Barnett manages a busy NHS practice as well as being H&N Service lead. Her aim is to increase the numbers of patients going into clinical trials.

Research Interests

My research aim is to individualize RT prescriptions, increasing dose in tolerant patients and modifying dose in sensitive patients. My work focuses on determining factors that influence the wide variation in RT toxicity. This includes patient-related factors, e.g. smoking; treatment-related factors, and genetic factors (radiogenomics). I am a co-investigator and local PI of RAPPER, a large UK radiogenomics study, and an active member of the international radiogenomics consortium.
