Abir Das

Welcome to my webpage

Hi, I'm Abir Das. I am an Assistant Professor in the Computer Science and Engineering Department at IIT Kharagpur. Before joining IIT Kharagpur I was briefly an Assistant professor at IIIT Delhi. I was a postdoctoral researcher at Boston University under Prof. Kate Saenko before that. I completed my PhD in Electrical Engineering from the  University of California at Riverside (UCR). My research advisor was Dr. Amit Kumar Roy-Chowdhury in the 'Video Computing Group' led by him. Before joinging UCR, I had done my Bachelor of Electrical Engineering from Jadavpur University, Calcutta, India in the year 2007.

Please visit the 'Research' page of this website to go over the research problems that I have explored in the past and am exploring recently.

PhD Positions
I am looking for highly motivated and talented PhD students interested to do do research on computer vision and machine learning. My interests lie in reinforcement learning, explainable AI and bias in Deep Learning models for Computer Vision. Interested students may look at my publications page and the research group page to get a glimpse of the kind of problems I am interested in.
