Dr. Chamith Abewardana Wijenayake is a Senior Lecturer (Teaching Focused) in the School of Electrical Engineering and Computer Science at the University of Queensland, part of the Faculty of Engineering, Architecture and Information Technology. He obtained his PhD in Electrical and Computer Engineering from the University of Akron, Ohio, USA, in 2014, and his BSc (Hons) degree in Electronic and Telecommunications Engineering with first-class honours from the University of Moratuwa, Sri Lanka, in 2007. Before joining UQ, he worked as a Lecturer in the School of Electrical Engineering and Telecommunications at the University of New South Wales, Sydney, Australia, from 2015 to 2019. His career has been marked by a commitment to both research and teaching excellence in electrical and computer engineering.

Wijenayake's research specializations include multidimensional signal processing, digital hardware architectures for signal processing, FPGA-based system design, hardware accelerators for machine learning, and engineering education. He has contributed significantly to the field through key publications such as 'Computationally efficient light field video compression using 5-D approximate DCT' (Journal of Low Power Electronics and Applications, 2025, with Sritharan et al.), 'Multibeam wideband transmit beamforming using 2D sparse FIR trapezoidal filters' (Journal of Low Power Electronics and Applications, 2024, with Dissanayake et al.), 'Real-time light field signal processing using 4D/5D linear digital filter FPGA circuits' (IEEE Transactions on Circuits and Systems II: Express Briefs, 2021, with Edussooriya et al.), and 'Online laboratories in modern engineering education: a systematic literature review' (book chapter, 2024, with Tomeo-Reyes et al.). His work demonstrates impact in areas like light field processing and low-power electronics. Wijenayake has earned major awards, including the Outstanding Student Research Award from the University of Akron in 2011, one of two IEEE Circuits and Systems Pre-Doctoral Awards in 2014, and a Citation for Outstanding Contributions to Student Learning at the Australian Awards for University Teaching in 2026. He has taught over 5,000 undergraduate students, innovating with interactive polling, video experiments, at-home lab kits during COVID-19, and coordinating large courses like Introduction to Computer Systems and Digital System Design, supported by grants from Echo360 and MathWorks. He also supervises PhD students on topics such as approximate algorithms for multi-dimensional array processing.
