In his groundbreaking book, Thinking with Your Soul: Spiritual Intelligence and Why It Matters, Dr. Wolman defines spiritual intelligence as: "the human capacity to ask questions about the meaning of life, and to experience simultaneously the seamless connection between each of us and the world in which we live." This book describes the creation of the PsychoMatrix Spirituality Inventory (PSI), which gives us a profile of our unique experience of spirituality, and the research that has flowed from it. This research, conducted at PsychoMatrix, is ongoing and continues to be the focus of lectures, workshops that highlight new findings and studies.

In addition to research on spirituality, Dr. Wolman's areas of interest and investigation include, child custody, Psychotherapy, Divorce, and Dreams. Publications on these topics may be found on Dr. Wolman's resume
