Ralph DaCosta, Ph.D

Dr. Ralph DaCosta received his PhD from the Department of Medical Biophysics, University of Toronto. His graduate research focused on the development and pioneering clinical application of advanced optical molecular imaging technologies for endoscopic diagnosis of early gastrointestinal cancers.

This work contributed to major improvements in the accuracy of conventional diagnostic endoscopy. These continue to directly benefit endoscopic cancer screening strategies around the world. Dr. DaCosta is an Assistant Scientist and Principal Investigator in the Division of Biophysics and Bioimaging, Ontario Cancer Institute, University Health Network (UHN). He is developing a comprehensive research program at UHN that focuses on accelerating the translation of these “bioimaging” capabilities directly into clinical practice. He also is a member of the Radiation Medicine Program (Princess Margaret Hospital) and the Spatio-Temporal Targeted and Amplification of Radiation Response (STTARR) Innovation Center at UHN.

Dr. DaCosta is one of Canada’s leading experts in the area of biophotonics. His ongoing contribution to the field of cancer imaging has been recognized by numerous awards and invited presentations at international meetings.
