Rangayyan received the 2013 Outstanding Engineer Award and Medal from IEEE Canada. IEEE, the Institute of Electrical and Electronics Engineers, is the world’s largest professional association for the advancement of technology.
The award recognizes an engineer for important contributions to electrical and electronics engineering. It was presented to Rangayyan in Regina on May 6 during the 26 Canadian Conference on Electrical and Computer Engineering.

Rangayyan’s contributions to biomedical engineering relate to signal and image analysis and include digital signal processing methods for noninvasive diagnosis of knee-joint cartilage pathology.

Rangayyan and his team were recognized last year with a Publication Prize from Canada’s Institute for Cancer Research for making a significant contribution to cancer research. They developed a software system that flags subtle signs of breast cancer sooner using advanced computer technology and mathematical algorithms to process images of mammograms and digitally analyze them.

The paper, entitled Detection of Architectural Distortion in Prior Mammograms, was published in Transactions on Medical Imaging, the most respected journal in its field published by IEEE.

Rangayyan has received a number of research excellence awards throughout his career. He has published more than 150 papers in journals and 250 papers in conference proceedings. He has written two textbooks and coauthored and coedited several more.
