Dr Harinarayanan is a consultant clinical oncologist who joined the Trust in 2017. He specialises in treating patients with head and neck and colorectal cancers using radiotherapy, chemotherapy and immunotherapy. He is the Trust's clinical effectiveness lead for clinical oncology.

Dr Harinarayanan is particularly interested in complex intensive modulated radiotherapy techniques in both head and neck and rectal cancers. His other clinical interests include:

  • re-irradiation (repeated radiotherapy) in rectal cancers

Key achievements

  • Dr Harinarayanan was involved in the low level laser therapy (LLLT) project for managing patients with head and neck cancer using radiotherapy. This project was the first of its kind in the NHS and implemented UHS as the pioneering cancer centre for LLLT. Since then, the technology has been approved by the Multinational Association of Supportive Care in Cancer and the National Institute for Health and Care Excellence.
  • He was ORF (Oncology Registrars Forum) representative for clinical oncology from the Wessex Deanery to the Royal College of Radiology from 2015 to 2016.
  • He changed the way journal club meetings in oncology at University Hospital Southampton were run, leading to a significant increase in attendance of junior doctors and consultants.

Awards and prizes

Dr Harinarayanan won a Wessex Shine award for implementing the out-of-hours cancer care management service at UHS. 


Dr Harinarayanan's research interests include:

  • immunotherapy trials in head and neck cancer
  • stereotactic radiotherapy (a technique that treats a tumour with radiotherapy from different directions) for head and neck and rectal cancers
  • proton beam radiotherapy (a type of radiation therapy that causes less damage to surrounding tissue) for head and neck and rectal cancers.
