Ass. Prof Charles Gillham graduated from University College London Medical School in 1994.

After attaining membership of the Royal College of Physicians in 1998, he started his training in Clinical Oncology on the Pan-Thames North East rotation. During this he worked at St Bartholomew’s, University College, The Royal Marsden and Mount Vernon Hospitals.  He became a Fellow of the Royal College of Radiologists in 2001.

On completion of his clinical training, he undertook an MD at Trinity College, Dublin in molecular and radiological response prediction in oesophageal cancer. This was followed by a fellowship (PET-CT/4D CT in lung cancer radiotherapy planning) at the University of Dresden, Germany.

He was appointed a Consultant in October 2008 and works at St James's and St. Luke's Hospital. He sub-specialises in the radiotherapy treatment of sarcomas, gynaecological, colorectal and haematological malignancies. He is the National Lead for Sarcoma, co-founder of the Irish Sarcoma Group and chairs their biannual meeting. He is an active member of Cancer Trials Ireland which has included being the principal investigator for ICORG 09-06 (a randomised trial of post-operative 3D conformal radiotherapy versus IMRT in uterine cancer), PORTEC4A (stratification of adjuvant therapy in early uterine cancer based on molecular signature) and IMRiS (prospective Phase II international trial of IMRT in soft tissue sarcoma).  He was an internal examiner for the School of Radiation Therapy, TCD 2009-2019 and since 2015 has been the Chief Examiner in Radiation Oncology for the Faculty of Radiology, RCSI. He was the clinical lead at the St Luke’s radiotherapy centre in St James Hospital (2013-2022) and since January 2023 the Network Director of the St Luke’s Radiation Oncology Network.
