Tong Leung

Director, Waterloo Advanced Technology Laboratory | Professor, Chemistry

Dr. Tong Leung is a chemical physicist working with emerging materials and their applications. His research explores the fundamental chemistry and physics occurring on the surfaces of novel materials, including low-dimensional nanostructural materials, as well as potential applications of these materials. He is the founding director of WATLab (www.watlab.com), a multidisciplinary research facility that provides advanced characterization and development of novel materials at Waterloo and beyond. 

Graduate Supervision: 

Dr. Leung supervises graduate students within the masters and doctoral programs in Chemistry and Physics. With diverse background in chemistry, physics and materials science, his students have, upon graduation, found employment in universities and national and international research laboratories in the areas of quantum computing, battery research, green energy, environmental remediation, and spin-based devices.
