About Us

I am a researcher in theoretical physics for more than 40 years. My post graduation in physics was, in 1971, from University of Kerala, and i was first ranker from entire state in that year. Thereafter I attended a one year training programme in Nuclear Science at Bhabha Atomic Research Centre, Mumbai. In a batch of more than 35 trainees, selected from all over India, I held second rank at the time of graduation. I joined the Theoretical Physics Division of Bhabha Atomic Research Centre in August 1972, as Scientific Officer, which is a post of gazette officer in Government of India service. Throughout my career, I have been involved in research programmes of theoretical, mathematical and computational nature which were necessary for different types of applications - civilian as well as strategic - of nuclear energy.

Initially for about twelve years I worked on applications of (fission) reactor physics for design and operational aspects of nuclear power reactors. This involved acquiring the necessary mathematical theory and models, adapting them to suit our specific requirements, implementation for computations and applications to reactor analysis. Thereafter, for more than sixteen years, I was mainly involved with similar responsibilities, but now for strategic applications. During all these years I also was keenly working on other topics, mainly in applications of statistical and mathematical methods. I also had a great opportunity to work with some of my esteemed colleagues in chemistry and solid state groups on soft matter physics.

As a theoretical physicist, I was leading the Theoretical Physics Division, consisting of more than 25 physicists, at Bhabha Atomic Research Centre, for about 10 years (April 2002 to October 2011). I was providing guidance in advanced research in theoretical work related to modelling, design and analysis of experiments for various applications of nuclear energy. In addition to fundamental and basic physics, our research work also included topics closely related to thermonuclear fusion and fission physics. Our studies in inertial confinement and laser driven fusion schemes enabled me to work in a number of current areas of investigations, like atomic physics of dense and hot plasmas, high pressure equation of state of materials, high temperature opacity of materials, hydrodynamics and shockwave phenomena, radiation transport theory, fission and fusion physics, etc.

Based on a course of lectures I gave at Theoretical Physics Division, I wrote a monograph titled "Renormalization Group Theory of Critical Phenomena" which was published by New Age International Publishers (Weily Eastern Limited). I authored /co-authored around 70 theoretical papers in reputed international journals. I also wrote similar number of documents and reports on topics related to my work at Bhabha Atomic Research Centre.

Apart from fulfilling official responsibilities, I had interest in a wide range of topics in theoretical physics and applied mathematics. I received PhD degree (in Applied Mathematics, Science stream) for my thesis, "Applications of Fourier Transform Methods to Resonance Absorption Phenomena in Nuclear Reactors", from Bombay University in 1978. For many years, I taught Reactor Physics, Statistical Mechanics, and Mathematics in the training division for physics trainees at Bhabha Atomic Research Centre. I also used to give advanced courses of lectures to physicists on renormalization group theory of critical phenomena, stochastic processes and applications, numerical methods for PDEs, etc.

I got very regular promotions at Bhabha Atomic Research Centre throughout my career. My last promotion, in the year 2007, was to the post of Distinguished Scientist which is the highest position for any scientific work in Government of India Service. I retired from service on 31 October 2011. However, I am continuing the research work, purely out of my personal interest, for I got immersed in this activity for a very long period.
