Chaminda Hewage is a Senior Lecturer in the Department of Computing and Information Systems in Cardiff School of Management in Cardiff Metropolitan University, Cardiff, where he also leads the Networking and Data Security disciplines at both UG/PG levels.

He received the B.Sc. Engineering (First Class Honours Degree) in Electrical and Information Engineering from the Faculty of Engineering, University of Ruhuna (Sri Lanka) in 2004 and the Ph.D. in Multimedia Communications from the University of Surrey (UK) in 2009. He was awarded the Gold Medal for best performance in Engineering (2014) by the University of Ruhuna for his achievements in undergraduate studies at the General Convocation held in 2004. In 2014, he received Post-Graduate Certification in HE Teaching and Learning from Kingston University – London. He is a Fellow of the Higher Education Academy (HEA), UK.

After graduation, he joined Sri Lanka Telecom (Pvt.) Ltd. (Sri Lanka) as a Telcommunication Engineer (2004). In Sep. 2005 he was awarded the Overseas Research Scholarships (ORS) award by the Higher Education Funding Council of England (Universities UK) to pursue Ph.D. at University of Surrey, UK. After completing his Ph.D. in 2008, he joined University of Surrey as a Research Fellow. In 2009, he joined WMN Research Group at Kingston University – London as a Senior Researcher. He is attached to the Computing Department at Cardiff Metropolitan University as a Senior Lecture since October 2015.

He worked as the Senior Researcher in a number of national and international research projects, funded by the European Commission (e.g., FP6 Visnet II, FP7 OPTIMIX, FP7 CONCERTO, FP7 Qualinet, FP7 3DConTourNet), UK research councils, Innovate UK, and industries.

An IEEE Member and he is part of international committees and expert groups, including the IEEE Multimedia Communications technical committee, where he serves as Web Manager of the 3D Rendering, Processing, and Communications Interest Group.
