Research Interests

I learnt  Descriptive Set Theory  and   Recursion Theory from Professor A. Maitra under whom I wrote my thesis entitled  Studies in Set Theoretic Hierarchies: from Borel Sets to R-sets. A.Maitra also induced me to learn Automata Theory. I then worked in Cellular Automata  and their applications. Currently my interests are in   Cryptography, DNA Computing and  Simple Voting Games .
