After completing the Masters in 2001 from the Department of Pure Mathematics, University of Calcutta, I joined the 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 the Indian Statistical Institute. During my Ph.D., I worked on Secret Sharing, Visual Cryptography, and Combinatorial Designs. After my Ph.D. 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 July, I joined the Department of Pure Mathematics, the 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, especially 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 the project, please click here.
