After completing the Masters in 2001 from the Department of Pure Mathematics, University of Calcutta, I joined Statistics and Mathematics Unit of Indian Statistical Institute, Kolkata as a JRF. After successful completion of the Course Work, I started my research on Cryptology under the supervision of Professor Bimal Ray, the former Director of Indian Statistical Institute. During my PhD I worked on Secret Sharing, Visual Cryptography and Combinatorial Designs.  After my PhD in 2004, I joined INRIA, Paris, France as a Post Doc Fellow and worked with Professor Anne Canteaut on Cryptographic Boolean Functions. Then I joined Linkoping University, Sweden as a Visiting Scientist and worked with Professor Erik Trell on DNA Secret Sharing. In 2006, in the moth of July, I joined the Department of Pure Mathematics, University of Calcutta as a Lecturer. I continued there as a faculty member till January 16, 2019.

Research Activities:

My broad area of research is Cryptology and Combinatorics. In cryptology, I am mainly interested in secret sharing schemes, specially visual cryptography. In combinatorics, I am interested in finding structures of critical sets in latin squares and graph coloring. I have active academic research collaboration with Kyushu University (Japan), University of North Texas, USA, University of Calgary, Canada,  University of Wollongong, Australia, Indian Statistical Institute, IIT Madras, IIT Kharagpur. In a nutshell, my research interest includes  Applications of Algebra, Graph Theory, Cryptography, Cryptanalysis of Stream and Block Ciphers, Secret Sharing, DNA Cryptography, Visual Cryptography, Image Encryption, Wireless Sensor Networks. I worked as a Principal and Co-Investigator of the twelve projects funded by DRDO, DIT, DST, DST-SERB, DST-FIST, NBHM etc. For more details regarding project, please click here.

Administrative and Professional Responsibilities:
1. Founder Secretary of the and  Institute for Mathematics, Bioinformatics, Information Technology and Computer Science (IMBIC), having branches in Sweden and Japan (since 2006).
2. Treasurer of Cryptology Research Society of India (CRSI) since 2008
3. Former NBHM Eastern Zonal Coordinator for conducting MSc and PhD Fellowship
Examinations in Eastern Region.

4. One of the Editors of the Research Monograph entitled "Mathematical and Statistical Applications in Life Sciences and Engineering" published by Springer, 2017.

5. Members od the Board of Studies of many institutes. 

My field of interest is Algebra and its applications to different interdisciplinary
fields such a cryptology, coding theory and graph theory. My future plan is to
offer few contemporary interdisciplinary topics in which students will explore
how their known knowledge of Abstract Algebra, Linear Algebra, Number
Theory are useful in solving real life practical challenging problems using the
concepts of cryptology, coding theory and graph theory. Apart from teaching, I am engaged with the following activities:

1. Worked as a paper setter, moderator, examiner of different examinations organized by different Universities and Institutes.

2. Worked as Thesis Reviewer of PhD Thesis of different Universities.
3. Worked as an external expert member of the Thesis Viva organized by different Universities.
4. Worked as reviewers of leading journals such as AMS Mathscinet, Discrete Mathematics, Discrete Applied Mathematics, Design Codes and Cryptography, IEEE journals, IEICE, many other Springer and Elsevier Journals etc
5. Worked as external Committee member of interview for the recruitment of Project Linked personnel at Indian Statistical Institute.
6. Worked as External Member for the M.Tech (CS) and M.Math Dissertation of Indian Statistical Institute.
7. Worked as a member of Board of Studies of different Institutions.
