Dr. Gedye is a medical oncologist and cancer researcher. He works for people with melanoma, brain, prostate, bladder and kidney cancers at the Calvary Mater Newcastle, NSW, Australia. His research focuses on complexity and heterogeneity in cancer. Why are cancers different between different people? Why are a cancer's cells different from each other? What does this mean for each person’s treatment? This challenging problem spans projects across the research spectrum, from patient experience, through clinical trials, translational biomarkers and questions in basic science. Craig is privileged to lead several clinical trials and cancer research projects for Calvary Mater Newcastle, NSW Regional Health Partners, ANZUP Cancer Trials group and COGNO, he chairs the ANZUP Renal Cancer Subcommittee, and is a member of the Mark Hughes Scientific Advisory Committee, HNELHD Clinical Trials HREC Subcommittee, COGNO Scientific Advisory Committee and ANZUP Cancer Trials Scientific Advisory Committee.
