PhD (Indian Institute of Engineering Science and Technology, Shibpur)
Research Interests: Cellular Automata, Theoretical Computer Science, Complex Systems, Art and Computation
Professor Roy did his Bachelor of Technology in Computer Science and Engineering from West Bengal University and Technology, Kolkata. Then, he obtained his Master of Engineering in Information Technology at the Indian Institute of Engineering Science and Technology, Shibpur. Professor Roy then did his Doctor of Philosophy in Engineering at the Indian Institute of Engineering Science and Technology, Shibpur. After that, Professor Roy pursued a Postdoctoral research fellowship as part of the C3iHub at the Indian Institute of Technology, Kanpur. From January 2023 to December 2023, he was an Assistant Professor at Bennett University, Greater Noida, India.
He is also a Moderator of the Cellular Automata India research group. For community research services, he acts as a co-organiser of the Indian Summer School on Cellular Automata Technology and the Asian Symposium on Cellular Automata Technology. He reviews theoretical computer science journals like the Journal of Cellular Automata and Complex Systems.
Professor Roy's research includes cellular automata, complex systems, and theoretical computer science, with a focus on the effect of perturbation in cellular automata. Currently, he is exploring the broad research question - "Does robust computation exist?" where he tries to solve real computational problems and technological solutions with the effect of noise. With this, he tries to understand the big philosophical question - "Does nature compute?". In particular, he is interested in models which make use of randomness to perform robust computation.
In this doctoral dissertation, he investigated distributed computing on cellular automata with application to societal problems which includes theoretical solutions of distributed computing problems and modeling societal distributed phenomena like riots using cellular automata. In his master's dissertation, he explored the theoretical properties of convergent discrete dynamical systems with the effect of noise.
He has also explored art, patterns, and computation, with a focus on patterns of chaotic systems, and symmetries within them. Professor Roy's computational patterns are exhibited in the Indian School of Logic and its applications, Asian Symposium on Cellular Automata Technology.
Professor Roy's research interest also includes the history and philosophy of computation. In this context, he is one of the co-authors of the book "The Mathematical Artist - A Tribute to John Horton Conway".
