Brief Bio

I am an Assistant Professor at the Department of Computer Science and Engineering, Indian Institute of Technology (IIT) Kharagpur. My primary research interests are in Social network analysis, Legal analytics, and Algorithmic bias and fairness. My research is inter-disciplinary and uses techniques from Machine Learning, Natural Language Processing, Information Retrieval, Computational Social Science, and Complex Network Theory. I head a Max Planck Partner Group at IIT Kharagpur, that focuses on algorithmic bias and fairness.

I received my PhD in Computer Science from IIT Kharagpur in 2013. I was a Humboldt Post-doctoral research fellow at the Max Planck Institute for Software Systems (MPI-SWS), Germany.

I am looking for motivated PhD students with strong technical (ML / NLP) and communication skills. Please email me if you are interested.

Note about internships: CSE, IIT Kharagpur has a summer internship program - you can apply here if you are interested. There is no scope for winter internship at IITKGP. I personally do not offer internships. Apologies for not being able to personally reply to the numerous emails asking about internships.
