I have done my Ph.D. under the supervision of Prof. Palash Sarkar at
the Applied Statistics Unit of Indian Statistical Institute, Kolkata.
From February 2015 to November 2016, I was a postdoctoral researcher in the AriC team
of LIP laboratory at ENS de Lyon hosted by
Dr. Benoît Libert. I spent one semester at the School of Electrical Sciences, IIT Bhubaneswar as an assistant professor (on contract). Currently, I am an assistant professor in the Department of Computer Science and Engineering at IIT Kharagpur. Here is my Curriculum Vitae.
Teaching
For Students
Please note that I DO NOT take interns. Neither do I respond to emails regarding the same.
