I am a Research Fellow at Secure Software Research Group, Department of Computer Science at School of Computing, National University of Singapore, where I am advised by Abhik Roychoudhury. The current focus of my research is on automated program repair, software security and software engineering automation. I obtained my PhD in Computer Science from the same group, during which my focus was on repairing software vulnerabilities using program synthesis, code transplantation and concolic repair.

Previously, I received a Bachelor of Science(BSc) Honors (Hons) degree from the Computer Science & Engineering Department at University of Moratuwa, Sri Lanka. During my bachelor degree I researched on automated solutions to proactively scale cloud resources. I've also worked as a Senior Software Engineer (Cloud/Security) at OrangeHRM on HR Tech where my focus was on System Security and Automation Technology.

Thanks to the support of my research mentors, I was fortunate to begin working on research early in my undergraduate career. I’m happy to help ambitious undergraduate students interested in software engineering get started with research, please feel free to email me!
