Mathematical Career

I am an Emeritus Professor of Mathematics, having taught at the University of Oregon from 1970 to 2000.   My main fields of research are Banach algebras and *- algebras.  I published a book summarizing my research fields; see the “My Book” tab.

In 1966, I earned a Ph. D. from Harvard University in Mathematics.  My thesis was in operator theory. While writing the thesis, I was able to dramatically shorten and simplify a formerly very complicated proof by using ideas from the theory of Banach algebras. Thus most of my professional publications since then have been about Banach algebras.
