I have completed my schooling from Birla High School, Kolkata and passed the Senior School Certificate Examination (Class XII) from CBSE board in 2006.

After my schooling, I pursued Bachelors of Technology (B.Tech) in Computer Science and Engineering from SRM University , Chennai, India in the year 2006-2010. I was awarded Gold Medal for the best outgoing student of the University.

During my B.Tech course, I got the opportunity to study in Massachusetts Institute of Technology (MIT), USA under semester abroad program for one semester in the year 2009. It was an enriching experience studying in MIT. Apart from the regular subjects, I took up a project on Natural Language Processing (NLP) under the guidance of Dr. David L. Brock (Principal Research Scientist, MIT) and Prof. Edmund Schuster (Principal Researcher, MIT) for which I got full academic credits. I was lucky enough to get a very good recommendation letter (it can viewed at Recommendation) from Dr. David L. Brock.

Alongside my work career as a software engineer, I completed Master in Engineering (ME) in Software Engineering from Jadavpur University (JU), Kolkata, India in the year 2012-2015. My Master’s thesis was in Network Security area and I did it under the guidance of Dr. Samiran Chattopadhyay (Head, Department of Information Technology, JU). My thesis can be viewed at Thesis.

1) I was selected in JENESYS (Japan - East Asia Network of Exchange for Students and Youths) program to visit Japan for 10 days as a cultural ambassador. The program was held during June 2009 and it was fully sponsored by the Japanese government. Those 10 days were the most memorable days of my life. I had attended conferences and gave presentations based on various aspects of India, Japan and rest of the world. I got the unique opportunity to stay with a Japanese family in the city of Miyazaki for 3 days. The overall trip was an enriching experience.

2) I was one among top 3 Indian students to be awarded Graham Bell Award 2010 by Aegis School of Business & Telecommunication, India.
