Biography:

I received my B.A, PGDip and M.Sc. degrees in Computer Science from the University of the South Pacific, FIJI in 1999, 2002 and 2010, respectively; and the Ph. D degree in Computer Science (in the area of Artificial Intelligence with specialisation in Computer Vision, and with applications to health informatics) from the University of Canberra, AUSTRALIA in 2021. My research work spans the areas of pattern recognition, computer vision and multi-modal information extraction and integration with a focus on brain-inspired cognitive architectures. I have also worked on the area of computer graphics with applications to facial expression generation and animation using Facial Action Coding System. I am also an adjunct Professional Associate with the University of Canberra, Australia.

COURSES Teaching:
Undergraduate Courses: CS001, CS111, CS112, CS241, CS341, CS400, IS122, IS222, IS226, IS314, IS333,

Research Interest

My current research work is centred around the areas of pattern recognition, computer vision and multi-modal information extraction and integration with a focus on brain-inspired cognitive architectures. The outcomes of my research are applied to improving the health and well-being of people; particularly in the area of melanoma detection using clinical and crowd sourced skin lesion images, and development of assistive feedback devices for the blind using live video feeds.
