Paul is an interdisciplinary cosmologist and independent scholar. Interdisciplinary cosmology offers a "bigger picture" than science's conventional view of reality. In addition to empirical research, it includes intuitive and other sources of knowledge, but subjects them to verification by the scientific method.
Paul believes a cosmology based only on a single discipline (whether physics, astronomy, biology, mathematics, evolutionary theory, or metaphysics) omits many areas of the human experience of the universe, including the mind of the cosmologist.
Given the quality of 21st-century consciousness research, an interdisciplinary cosmology would suggest a dimension of consciousness (conterminous, coterminous, and coincident with matter and energy) animates all life forms in a universe of multiple dimensions. The Science and Spirituality.net website describes the work of Paul and others who seek to grasp such a "macro" view of reality.
His current work involves the Reincarnation Experiment and his new book The Soul Genome: Science and Reincarnation.
