He has also done research for Litton Industries, United Technologies, and NASA as well as through Oman Consulting, Inc. He is author of numerous technical articles, books, CD's and how-to-study books, tapes and videos.

His academic work includes teaching mathematics and physics at the undergraduate and graduate levels.

His research is in both the academic and industrial environment. His areas of research include electromangnetic theory, semiconductors, gas reactions, physical electronics, biology, magnetic materials, upper atmosphere physics and vacuum measurement. He holds patents on electromagnetic devices, sputter deposition devices, vacuum gauges, and infrared image devices. His complete theory of electron mirror microscopy is published in the Encyclopedia of Electronics and the vacuum gauge he designed was the first pressure gauge placed on the moon. Subsequently this gauge was sent on solar travelers.  Ever the practical scientist he has worked on environmental problems, ocean farming, highway safety and combining a life-long interest in auto racing consulted with Century Racing on chassis design and vehicle handling.

For his work in mathematics and physics he was named one of the top 2000 scientist of the 20th Century by Cambridge (England) University.  He is a member of Sigma Xi

Most recently he has devoted his efforts to teaching, writing (three books for McGraw-Hill, one for Burgess and a CD for Wiley and three websites), and consulting.
