Frank Lee has background in physics, control engineering, and biomedical sciences. He has published a few papers in peer-reviewed scientific journals, including four papers on the gating mechanisms of ion channels. The combined background in engineering, physics and biology, together with specialty in ion channels, stimulated the idea that ion channels might act as "transmitting antennas" for wireless communication in the brain.

Frank is a Christian. He strongly believes in the existence of God and soul. However, being trained in physics, he would like to think of God and soul from a scientific perspective, such as the view described in the article, "Why Can't We See God - A scientific explanation" (posted on Easter, 2005). This understanding also caused him to realize that, under special circumstances, we could "peek into Heaven".

Then, what is the soul? According to the "string theory" of physics, only gravitational waves can enter ten-dimensional (10) space. All other things that we know of (including electromagnetic waves) must be confined in the 3D world that we live. Therefore, if Heaven (or spirit world) is located in the 10D space and the soul is something that can enter Heaven, then it must be composed of gravitational waves only. In physics, such entity is known as a "gravitational geon." Further details are given the book:
