Professor Hicks has made major contributions to the care of patients with cancer through his pioneering work with positron emission tomography (PET), which has now become a routine imaging test for selecting and monitoring cancer therapies. By applying this technology in translational research he has helped develop new cancer therapies, especially targeted drugs for malignancies previously without effective treatments. He is also an international leader in the field of neuroendocrine tumours, in which he has pioneered new forms of internal radiation delivery in combination with chemotherapy. He sits on multiple editorial and scientific boards and is Editor-in-Chief of Cancer Imaging.
