Biography

Ranjith Liyanapathirana received his BScEng(Honours) degree in electronic and telecommunication engineering from the University of Moratuwa, Sri Lanka in 1981 and his MEng and PhD degrees in electrical engineering (signal processing and communications) from the Memorial University of Newfoundland, St. John's, Canada in 1987 and 1995, respectively.

He was an Assistant Lecturer in the Department of Electronic and Telecommunication Engineering at the University of Moratuwa (1981-1983); a Telecommunications Engineer with Saudi Telecom in Riyadh, Saudi Arabia (1983 to 1984); a teaching assistant in the Department of Electrical Engineering at the Memorial University of Newfoundland (1985-1993); an Associate Lecturer in the Department of Electrical and Electronic Engineering at the University of Western Australia (1994-1995); and a Research Fellow in the CRC for Broadband Telecommunications and Networking in Perth, Australia (1996-1998). In 1998, he joined the University of Western Sydney as a lecturer in the School of Mechatronic, Computer and Electrical Engineering, and is currently a Senior Lecturer in the UWS School of Engineering.

His areas of research interest are information theory and coding, mobile communication, biomedical engineering and civionics. He is a member of the IEEE and the Australian Computer Society (ACS). He has a hobby interest in amateur radio (VK6BHV).
