During his thirty-six year tenure, he engaged in both conventional studies on aging and cancer, and also in studies of bioenergy. In 1957, he became acquainted with the gifted healer, Oscar Estebany. He served as the primary healer in Dr. Grad's pioneering studies on the effect of laying-on-of-hands on laboratory animals and plants. These studies demonstrated clearly that such healing was not due to suggestion but was basically dependent on a bioenergetic interaction between healer and organism being healed. Dr. Grad is the author of more than 130 articles, many of which are about healing.
