Research Profile

Amal Punchihewa obtained a Bachelor of Engineering, specialising in Electronics and Telecommunication Engineering, from the University of Moratuwa in Katubedda, Sri Lanka, with honours in 1986. In 1991 he completed a Master of Electronics Engineering at the Technical University of Eindhoven, The Netherlands, focusing on digital video signal processing. Amal has worked as an engineer in both academia and industry over the past thirty-four years, starting as a computer engineer in 1986. After three years he moved to the broadcast industry, working as a research engineer for the national television broadcaster in Sri Lanka. In 1994 he became a senior lecturer at the University of Moratuwa, before migrating to New Zealand in 2002, where he joined Massey University in Palmerston North. His PhD was on a framework for rapid evaluation of image and video compression artefacts objectively. He is a researcher and educator. His current research interests are disaster management and communication, accessibility, inclusive media and learning technologies, smart homes and cities, ICT policy, objective assessment of compression artefacts and image processing for surveillance, multimedia communication and care of the elderly. Amal is a Fellow of the Institution of Engineering and Technology (UK), a Fellow member (Rtd.) of Engineering New Zealand, senior member of IEEE-USA and a life member of the Sri Lanka Association for Advancement of Science. In 2000 he was awarded a prestigious on-the-job research award (the Wimalasurendra award) in recognition of the contribution he made to the broadcasting development by the Institution of Engineers Sri Lanka.

He has published over 120 scholarly articles (peer-refereed technical journal and conference articles) in various journals including IEEE and IET digital libraries and transactions. He has held visiting positions at Tokyo University of Science (Japan) as a visiting associate professor and visiting professor. He was a Royal Dutch fellow of Netherlands and Japan Society for the Promotion of Science (JSPS of Japan). He has served on technical/programme committees, organizing committees and as track/session chairs for many international conferences. He was an advisor on many International conferences including CCBN conference in China, BES in India and BCA in Singapore.

Amal was the Director Technology & Innovation at a professional organisation of radio, television and media. In that position, Amal led the innovation of media technology in the complete chain of media, starting from acquisition to consumption in the broadcasting industry. He influenced the development of media technology in the best interest of its members. He led a team of specialists, he facilitated technical guidelines and standards and provided expertise related to the convergence of media and evolving technology needs. He created, encouraged, and managed member communities, and understood and explained the trends that shape the media, to empower Members to continue to take good strategic decisions.

He ensured that the work he led continues to be vital and respected by its members and the media industry. As a member of the Senior Management Team, he also played a major part in shaping its strategy.

Amal was active in many of the World Broadcasting Unions – Technical Committee (WBU-TC) and International Telecommunication Union (ITU) broadcast-related technical activities. He was Vice-Chairman of the WBU-TC for four years. He is an advisor to IET Vision and Imaging Professional Network having served as an executive of IET Vision and Imaging Professional Network in the UK.

He possesses more than 34 years of experience in all three sectors of ICT, media and broadcasting; viz. Academia, Research and Industry in senior broadcasting technology and ICT roles, including research and developments, regional capacity building in media and head of engineering of national television broadcaster in Sri Lanka, having started the career in computer engineering.
