Abhijat Biswas

I am a PhD student in the Robotics Institute at Carnegie Mellon University, working with Henny Admoni on using driver eye-gaze information to inform active sensor policies for safer autonomous and assisted driving. I worked with Henny and Aaron Steinfeld, on social navigation and related topics for Human-Robot Interaction during my Masters.

Previously, I've spent time teaching neural nets to recognize free hand sketches at IISc Bangalore. I've also worked on using temporal smoothness in videos as supervision for neural networks at Cardiff University. I went to IIT Guwahati for ECE.
