Research Summary

Our group’s aim is to develop strategies to increase the efficacy of radiotherapy treatment. This work often involves repurposing existing compounds, or developing new treatments, that can be effectively combined with radiotherapy. Where possible, we seek to translate our laboratory findings into clinical trials utilising functional imaging and genomic data to provide signals of pharmacodynamic efficacy. 


Geoff Higgins is the Malcolm & Margaret Howat Associate Professor in Clinical Oncology.

He obtained degrees in pharmacology (1997) and medicine (2000) from Edinburgh University and undertook specialist training in Clinical Oncology at the Edinburgh Cancer Centre. He subsequently moved to Oxford and was awarded a Royal College of Radiologists/CRUK Clinical Research Fellowship leading to a DPhil in 2010. Geoff subsequently obtained his Clinician Scientist and Advanced Clinician Scientist Fellowships from Cancer Research UK.

His research includes laboratory and clinical research aiming to improve the efficacy of radiotherapy treatment. He is currently the Chief Investigator of two clinical trials and is joint-lead investigator of the CRUK National Cancer Imaging Translational Accelerator.
