Hany Aziz is a professor in the Department of Electrical and Computer Engineering with a cross-appointment to the Department of Chemical Engineering. He served as the Associate Director of Waterloo’s Nanotechnology Engineering program from 2015-2019. He is also Associate Director of the Giga-to-Nanoelectronics Centre. He previously held the appointment of NSERC- DALSA Research Chair in organic electronics.

Professor Aziz’s group conducts research in the interdisciplinary area of organic electronics and optoelectronics including both electroluminescent (such as Organic Light-Emitting Devices or OLEDs and quantum dot LEDs ) and light harvesting (such as organic photovoltaics and optical sensing) materials and devices. The research spans a wide range of areas ranging from studying fundamental phenomena in organic semiconductors (such as carrier injection and transport, exciton dynamics, carrier-exciton interactions) to developing novel devices and fabrication technologies for next generation electronics (such as flexible flat panel displays and printable electronics).

Professor Aziz’s research contributions are widely cited in the organic electronics community, and have resulted in over 150 peer-reviewed publications to date. He has several inventions including the industry’s benchmark long-life and thermally-stable OLED and the contrast enhancing Black Cathode™ Technology. He holds 51 U.S. patents. In 2020 he was awarded a University Research Chair.
