Solved a 40 year old conjecture on the existence of self-complementary circulant graphs stated by Horst Sachs.
Developed "A Theory of Cartesian Product and Factorization of Circulant Graphs" similar to the theory of product and factorization of natural numbers.
Defined a new type of circulant graph isomorphism, developed its theory and obtained new abelian groups.
Defined 'Sigma labeling' of graphs or Distance Magic labeling of graphs and developed its theory with Dr. M.I. Jinnah.
Extensively studied properties of sum and integral sum graphs.
Five candidates completed their Ph.D.s under my guidance. Published 22 papers in National/International journals and 35 articles in proceedings of National/International Conferences.
