I was awarded tenure after the upper paper was circulated, well before it appeared in print. As you can see by the dashed red box, the top publication has been referenced in over 4000 published papers.

I am eternally grateful to Alan Laub who went on to a sterling career in academics. He taught me so much, and we had loads of fun working together.

From the upper work, I became convinced 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.
