Biography Summary

En-Hui Yang is an Electrical and Computer Engineering Professor and founding director of the Leitch-University of Waterloo Multimedia Communications lab. He is also the co-founder of SlipStream Data Inc. (now a subsidiary of BlackBerry Inc. formerly known as Research In Motion), and a past associate editor for IEEE Transactions on Information Theory. Professor Yang holds a Canada Research Chair (Tier 1) in Information Theory and Multimedia Data Compression.

Professor Yang is the co-developer of the Yang-Kieffer algorithm, a numerical set of rules that use grammar-based coding to achieve lossless compression of text and image files, and also the co-inventor of soft decision quantization (also knowns as rate distortion optimization quantization or trellis quantization), an efficient coding technology widely used in image/video application related products (such as smart phones, web browsers, etc.) for better compression. With research interests ranging from multimedia compression, information theory, digital communications, image and video coding, image understanding and management, big data analytics, to information security, he aims to develop technologies that will enhance the storage capacity of computers, make the transmission of data faster and more reliable, secure data anytime and anywhere, and/or make big data understandable.
