With wife and colleague, Alyce Green, he authored a number of papers and wrote a book, Beyond Biofeedback. He is a member of several professional societies and advisory boards. For 20 years he and Alyce lectured and conducted workshops on the Theory and Practice of Biofeedback Training for Psychophysiologic Self Regulation, in the United States, Australia, Canada, India, Great Britain, Holland, the Philippines, and the Soviet Union.

In recent research (a study of psychophysics and psychophysiology during a form of Tibetan meditation), he and his colleagues found anomalous electric-field effects in and around the bodies of well-known "healers." A video documentary of this phenomenon, made with the cooperation of healer Mietek Wirkus, is called, Bioenerqy: A Healing Art (Peter Walsh producer, Media Production Group, 360 Highland, San Francisco, CA 94110).
