Ramanathan Subramanian
Adjunct Research Scientist

Ramanathan Subramanian is an adjunct Research Scientist at ADSC, and his research focusses on Human-centered computing, which involves design and implementation of AI systems with the human as an integral part of the loop. In particular, he is interested in developing methods to understand human visual and emotional perception as well as human behavior. Earlier, he was a Post-doctoral Research Fellow at the Department of Computer Science and Information Engineering (DISI), University of Trento, Italy, where he worked with Prof. Nicu Sebe.

Research Interests: Human-centric design/computing, Human-behavior understanding, Brain-computer interfaces, Human-computer interaction, Multimedia processing, Computer vision, Machine Learning
