I am currently a PhD student at the Indian Statistical Institute, Kolkata. I have done BTech and ME in ECE. My research area includes brain-computer interfacing and human-computer interaction for robotics and rehabilitation, gesture recognition for healthcare, energy management for smart buildings and evolutionary optimization algorithms. For all of the above research, I intensively use and rely on MATLAB.
