I have given over a dozen talks at various venues, including book stores, libraries, restaurants, as well as organization, such as Rotary clubs. My presentation usually centers on all aspects of the self publishing process, including my motivation for becoming an author, and a little about my books, especially the thriller which is of more general interest.

I live is a Carmel NY (a Rotarian, and a past president), but spend winters in Lake Worth FL. I wrote two books. One is the Daughters of Ishtar, a thriller about a contemporary spiritual group, with roots from a pre-biblical matriarchal society, which aims to rework all mankind. The other is The Gyroverse, a nonfiction book on an original theory that unifies all physics and explains many of the anomalies that have stymied the physics community.

While previously employed at IBM, I received many patents and presented original research papers on diverse technical subjects at major scientific conferences. These include conferences sponsored by The New York Academy of Sciences, The Annual Conference on Engineering in Medicine and Biology, The Numerical Control Society, and The Eastern Joint Computer Conference.
I received a Bachelor of Electrical Engineering from The City College of New York, and a Master of Science in Electrical Engineering from Syracuse University. I also have completed all coursework toward a Ph.D. in Mathematics at New York University.

The Daughters of Ishtar, is devoted to reestablishing their long defunct matriarchal society. This ancient society, one of the most advanced in history, had a scripture that became the template for the Hebrew Bible. Several times in history the group attempted and failed to reestablish their society, most significantly two thousand years ago by the most maligned female biblical character.
