International Publications while in Toronto:
In Toronto I was especially fortunate to work with Professor W. Murray Wonham and Professor A.J. (Alan) Laub. From them I learned Professor Wonham’s geometric approach to linear multivariable control theory, and from Alan I learned numerical linear algebra. Alan and I joined the University of Toronto at the same time and worked together for two years. Together we introduced the concepts and methods of numerical linear algebra into the domain of linear systems theory. He went to on to a sterling career in academics where he contributed enormously to the understanding of high precision computational methods. Largely because of the work in that top paper to the left (presented in lectures and conferences long before it was published) I was awarded tenure in 1978. As you can see by the dashed red box, the top publication has been referenced in 3555 papers.
A surprising side effect of the research that brought academic tenure was this: I became convinced me that vector-space methods are seriously flawed for the kind of industrial applications I wanted to pursue. So, I left academics for hands-on work in industry back in Louisiana where I could explore computation and mathematics in the real world of industrial production. The big bonus was that my children would grow up near their grandparents.
