Dr. Nalin A. G. Arachchilage

Dr. Nalin Asanka Gamagedara Arachchilage is a Senior Research Fellow (Research Associate Professor in US) in Cyber Security within the Department of Computer Science and Information Technology at La Trobe University, Australia, where he currently leads the Usable Security Engineering Research Laboratory (USERLab) in the Optus La Trobe Cyber Security Research Hub. Previously, he was a Lecturer in Cyber Security in the School of Engineering and Information Technology of the University of New South Wales at the Australian Defence Force Academy (ADFA), where he led the Usable Security research group. He holds a Ph.D. in Usable Security entitled “Security Awareness of Computer Users: A Game-Based Learning Approach” from Brunel University London, UK where he developed a game design framework to protect computer users against “phishing attacks”. Prior to undertaking his current position at UNSW, he worked as Research Fellow in Usable Security and Privacy in the Laboratory of Education and Research in Software Security Engineering (LERSSE) at the University of British Columbia (UBC), Canada.

Before moving to Vancouver, he was a Postdoctoral Researcher in Systems Security Engineering in the Cyber Security Centre, Department of Computer Science at Oxford University. His primary research interests are at the intersection of computer security, human computer interaction (HCI), and on-line privacy, in an area known as usable security and privacy engineering. Many aspects of computer security synthesise technical and human factors. If a highly secure system is unusable, users will try to by-pass the system or move entirely to less secure but more usable systems. Problems with usability contribute to many high-profile security failures today in the technology-filled world. His goals are to investigate how users manage their security and privacy in existing systems in order to design new systems that achieve better privacy and security solutions by taking end users into account. Nalin has over 60 publications and his paper entitled “Why developers cannot embed privacy into software systems?: An empirical investigation” has received the best paper award in the 22nd International Conference on Evaluation and Assessment in Software Engineering 2018, ACM (EASE’18) [A ranking]. Nalin has presented his research at Facebook Headquarters, Menlo Park, California, USA and collaborated with HP in a research capacity at the HP Lab, Bristol, UK. His is research has been featured in numerous media outlets including ABC News Radio, 2GB 873 AM Radio, SYN Radio 90.7 FM, Sky News Australia, Daily show on Radio 2SER 107.3, Choice – Australia, Guardian labs (sponsored by Intel Corporation, Australia) and UNSW TV.

He has been an invited speaker for conferences both nationally and internationally. Nalin worked on a number of academic positions in Computer Science at Brunel University, University of Bedfordshire, Westminster University and Central Bedfordshire College in the UK. Before moving to UNSW, he briefly worked as Sessional Lecturer in Computer Science at Deakin University, Victoria University and Central Queensland University (CQUniversity) in Melbourne, Australia. He obtained a BSc (MIS) Hons from University College Dublin, National University of Ireland and has completed a master’s degree, MSc in Information Management and Security at the University of Bedfordshire, UK. He is a Sun Certified Java Programmer (SCJP) at Sun Microsystems (now Oracle), USA. He is also a professional member of Association for Computing Machinery (MACM), the Institute of Electrical and Electronics Engineers (MIEEE) and the Australian Computer Society (MACS). Apart from his academic career, he also worked on a number of software engineering roles ranging from Programmer, Software Engineer to IT Manager.
