I am a PhD student in Computer Science at The University of Adelaide. Prior to joining UoA, I worked as a junior academic staff member and a research assistant at the University of Colombo, Sri Lanka. I also worked as a System Developer for a Virtual Rehabilitation project at Monash University, Malaysia. Before my academic career, I worked in the software development industry in Sri Lanka. 

My main research interests include conducting empirical software engineering studies to research security in the DevOps paradigm, mining software repositories using text mining techniques and human factors or socio-technical research. I also have a particular interest in studying cognitive factors involved in fast-paced and highly collaborative software development environments.
