I am a computer vision and Data analytics scientist and an engineer with a focus on machine vision application. Mainly interest on very large scale analytic to understand human behaviour using multi modalities (audio, faces & gestures) specially, in educational, behavioural science and entertainment domains such as Televisions, Movies, Netflix etc..). I have work experience in domestic and international industries as an Engineer, Scientist and in academia. Beyond my background in computer vision and applied machine learning, my research often assimilates data science, large scale video data analytic, artificial neural networks, image processing, natural language processing, bio-medical engineering and human computer interaction.
