I am a semi-retired United States Army, Military Intelligence Officer. I hold a B.A. from the University of Hartford, and a M.A. from the University of Connecticut. My primary military specialties were in cryptography, technical intelligence and electromagnetic combat. My secondary specialties were in nuclear, biological and chemical warfare. In terms of hobbies I am active in a local astronomical society and the New England Antiquities Research Association. I also enjoy fishing and travel. At present I have authored one book on military related service and am working on further publications. I like to stay abreast of developments in science and technology and use GeoGebra to explore advanced concepts in analytic geometry. As a former senior DOD cryptographer I am well acquainted with the relationship between geometry, math and cryptography. I have found GeoGebra to be an excellent vehicle for exploring advanced concepts in geometry in a easy to grasp manner.
