I am a retired Chemical Engineer who worked for over 35 years for a large San Francisco engineering firm. The majority of my project assignments were in the field of uranium/plutonium processing of both civilian nuclear fuel and government weapons-related materials. I worked on a variety of projects at the Department of Energy's nuclear weapons development laboratory at Livermore, California.

Although Project Yellow Sky is a purely fictional account of a plot to steal nuclear weapons material processing secrets from Japan and the U.S., it is based in large part on my own experiences at Livermore as well as the current North Korean nuclear threat to the free world.
