Very good foot-ball player/ play maker/ strategist. Specializes in Graph theory, Combinatorics, Algebra, Real and Complex Analysis. Solved a 1962 conjecture on the existence of self-complimentary circulant graphs stated by Prof. Horst Sachs of Germany. Defined sigma labeling (now it is known as distance magic labeling) and developed its theory with Prof. M.I. Jinnah. Defined a new type of circulant graph isomorphism and developed its theory – My Ph.D. thesis work. Developed a theory of Cartesian product and factorization of circulant graphs similar to product and factorization of natural numbers. Extensively studied sum and integral sum graphs and vertex self-switching of graphs. “The Four Color Theorem – A New Proof by Induction” – a 30 years of work on 4CT and “Generating prime numbers – A fast new approach” – a mile stone in Number Theory are put in arXiv on 11.01.2017 and 26.04.2019, respectively. Visited Universiti of Brunei, Brunei (1995) and American University of Sharjah, Sharjah (2017). Delivered several invited talks in conferences/seminars. Published 53 research articles & successfully guided 08 M.Phil. and 06 Ph.D.s. At present, guiding 03 Ph.D. research scholars.
