I joined the UL Lafayette faculty in 1968 and was one of the developers of the then new Ph.D. program, which began in 1968-69. I have been active in the Ph.D. program ever since. Thirteen students have written Ph.D. dissertations under my direction, the first finishing in 1973, with a dissertation in computational near-ring theory, and the most recent in 2011, with a dissertation in ring theory. My research interests have included: near-rings, rings, semirings, universal algebra, groups, semigroups, operational calculus, equivalents of the axiom-of-choice, ordinary differential equations, operational calculus, biomathematics, and the history of mathematics, with publication in each of these areas. Most recently my main research interest and publications have been on semigroups arising from rings. In 1980 I was a research fellow at NASA and in the late 1980's to 1995 was a consultant for a major oil company. In 1976 I received a UL Lafayette Distinguish Professor award. Although I retired from full time duties in 2004, as an emeritus professor, I have stayed active in research and teaching. Since 2004 three doctoral students have done dissertation research under my direction, almost every Spring semester I teach our History of Mathematics course, and occasionally have students do individual study courses with me. I have continued to be a member of the UL Lafayette graduate faculty and am active in our department's graduate program. At present I am a reviewer for A.M.S. Mathematical Reviews and for MAA book reviews.
