About Me




My research interests span all aspects of cryptography, with special focus on cryptographic complexity, encrypted computing, and the design and implementation of real world cryptographic protocols.  

I received my B.Tech in 2015 and PhD in 2019 from the Department of Computer Science and Engineering, Indian Institute of Technology Kharagpur. I was very fortunate to have Dr. Debdeep Mukhopadhyay as my PhD advisor. 

I had a wonderful experience visiting the Cryptography and Information Security Lab, IISc Bangalore, where I was hosted by Dr. Arpita Patra during September-October 2019.

I spent the summer of 2019 interning at Visa Research, Palo Alto, CA, where I worked with Dr. Pratyay Mukherjee, Dr. Daniel Masny and Dr. Shashank Agrawal.

I spent the summer of 2018 interning at Fujitsu Labs of America, Sunnyvale, CA, where I worked with Dr. Hart Montgomery and Dr. Arnab Roy.

I had a wonderful experience visiting the School of Computer Science and Engineering, NTU Singapore, where I was hosted by Dr. Thambipillai Srikanthan during January-June 2017.

I spent the summer of 2016 interning at IBM Research India, where I worked with Dr. Prasad Naldurg and Dr. Sameep Mehta.

I am grateful to IBM Research IndiaIntel Labs OregonQualcomm India and the Department of Higher Education, MHRD, Govt. of India for their generous fellowship supports during my PhD.
