Hadamard matrices, Orthogonal designs and applications

Office Hours

MWF 11:00 AM to 1:00 PM

About Me

I am interested in design theory and related applications. More specifically, I work on Hadamard matrices and designs. A very special class of Hadamard matrices which I have called them to be of "Bush-type" has proven to be extremely interesting. A recent result of Muzychuck and Xiang establishes the existence of these matrices for many interesting orders, but of course, we need to investigate the existence of many more. A very recent link found between these matrices and the "energy of graphs" has made them so much more interesting.
