Introduction


Success is no accident. It is hard work, perseverance, learning, studying, sacrifice and most of all, love of what you are doing or learning to do. ---------- Pele

I am a researcher in applied cryptography and computer security. My vast area of research is in Searchable Encryption. Besides theoretical aspects I like to implement to check scalability and efficiency in real environment. I am currently working on "Searchable Symmetric Encryption" under supervision of Dr. Sushmita Ruj.


I did project on Bitcoin Transaction Graph Analysis. I studied Bitcoin with my own interest. Now I am very much interested to explore Blockchain Technology and its real world applications.


Here is my CV (Last Updated: January 2018).


I Like to read books. I have a hobby to collect most famous books around in the world.
