Biography

Chathu Ranaweera is an associate professor in computer networks and the course director of Master of Information Technology course suit at Deakin University. She received her PhD from the University of Melbourne in 2014. She has held several positions prior to joining Deakin including a research Fellow at the University of Melbourne, a visiting researcher at AT&T Labs Research, USA and KTH Royal Institute of Technology, Sweden.

Her research primary focuses on enabling high-bandwidth, reliable, secured, and ubiquitous internet connectivity from anywhere at any time in a cost effective and energy efficient manner. She has been serving as a member of Optics Roadmap working group in IEEE Future Networks, and technical program committee member of several leading conferences in her field including Optical Fibre Communication Conference (OFC), IEEE International Conference on Communications (ICC), IEEE Photonics Conference (IPC), Conference on Lasers and Electro-Optics (CLEO), IEEE International Conference on Network Protocols (ICNP), International Conference on Networks, Communication and Computing (ICNCC), and International Conference on Optical Network Design and Modelling (ONDM).

Dr Ranaweera is a passionate educator, and her teaching philosophy is centred around” Lifelong Learning” - the learning is a lifelong process, and we need to motivate students to become a lifelong learner so they can be successful in their life in this rapidly changing world.  She is also a passionate advocate of women in STEM and is leading several initiatives to help and inspire young women to study and stay in STEM including leading projects with Victorian schools.
