Mohammad Bsharat, "On the Existence of Balanced Arrays with Two Symbols", PhD thesis, 2002
Professor Chopra's research interests are in the areas of Statistical
Design of Experiments, Combinatorial Mathematics, and Graph Theory. A part of
his publications include numerous papers on the construction of optimal
fractional factorial designs, some of which have been shown to be optimal in
the class of all fractional factorial designs. He has published extensively on
some combinatorial arrays such as Balanced Arrays and Orthogonal Arrays. He
has also made contributions to the area of Graph Theory, in particular dealing
with edge-balanced graphs. He has presented invited/contributed papers at various National/International conferences.
