About me

I got my first appointment as a Temporary Instructor in 2003 at the University of Colombo School of Computing (UCSC). Later, I got promoted to a Temporary Assistant Lecturer. Then, in 2006, I assumed my duties as a Lecturer. Now, from 2015, I’m serving as a Senior Lecturer.

I got my PhD at the Department of Computer and Systems Sciences (DSV), Stockholm University, Sweden, in 2015.

I completed my B.Sc. (Honors) in Computer Science at University of Colombo in 2003 and MPhil degree at the UCSC in 2009.

My research interests are in Affective Computing, Embodied Cognition, Cognitive Robotics, Embedded Systems, and Simulation-based Training. I have a special interest in Philosophy of Mind.
