He received his MD, PhD from the University of Toronto (1992; 1997) with post-graduate training at the MD Anderson Cancer Center, Massachusetts General Hospital and Erasmus University-Rotterdam. His laboratory has shown that the tumour microenvironment alters DNA repair which may be Achilles heel in resistant cancer cells. He is currently developing novel genomic signatures relating to DNA repair and prostate cancer to predict treatment response. Dr Bristow is currently Co-Director of the STTARR Innovation Imaging Facility (MaRS Complex) and is Lead for the Canadian Prostate Cancer Genome Sequencing Project (CPC-GENE); part of the International Cancer Genome Consortium (ICGC).
