Professional background

Dr Dawn Carnell is a consultant clinical oncologist based at University College Hospital London since 2005, working and teaching within an exceptional multidisciplinary team of dedicated professionals in head and neck cancer. 

She trained at The Royal Marsden and University College Hospital. Her UCL research (MD), CRUK sponsored, investigated cancer hypoxia and Blood Oxygen Level Dependent (BOLD) Magnetic Resonance Imaging, led to translational research for radiation dose escalation aiming to achieve higher cancer cure rates. Intensity Modulated Radiotherapy is given as the standard of care with concurrent chemotherapy, immunotherapy and molecular targeted treatments where indicated. She has a particular interest in sinus tumours, including rare olfactory neuroblastoma and peri-orbital tumours, where tailored surgery and proton beam therapy can deliver an effective cure with reduced late effects. Proton Beam Therapy, now available at University College Hospital, is of value for younger patients or where the tumour is close to radiosensitive tissues. Dr Carnell is part of the proton head and neck multidisciplinary team delivering this treatment where clinically indicated and offering national studies.  

Qualifications:  

  • BSc (University of London RFHSM) Immunopathology 1989 
  • MBBS (University of London) Merit in Medicine and Surgery 1991 
  • MRCP (UK)1996   
  • FRCR 2000 
  • MD (UCL) 2012 
  • GCP (current)

Research interests

Her research interests include the technical delivery of radiotherapy whilst minimising late effects - national studies such as PARSPORT, COSTAR and PET-NECK, UCLH based PET and Functional MRI radiotherapy studies and fibrosis/late effects trials in head and neck cancer. Principal Investigator at UCH for the PROTIS trial - opened October 2025.
