Sanka Rasnayaka

I am a Teaching Assistant and a PhD candidate at the School of Computing in National University of Singapore.

My research is on Continuous Authentication for modern personal devices, with on-body gait biometric. I have submitted my final thesis for examination under the supervision of Prof. Terence Sim.

My teaching philosophy is to facilitating self-learning by guiding the students thinking toward the final learning outcome, rather than explaining to them how to get there. I enjoy teaching fundermental courses in Computer Science like Discrete Structures, Programming, Algorithms and specialized courses in AI, Machine Learning and Computer Vision.
