Charles T. Krebs began his professional career with a PhD in Biology & Physiology from Boston University. After teaching marine biology and neuroanatomy for a number of years at St. Mary's College in Maryland, in 1983 he moved to Australia as a Marine Research Scientist at the Marine Sciences Laboratory in Queenscliff, Victoria. Shortly after his move, a near fatal scuba diving accident left him paralyzed from the waist down and opened the door to a new chapter in his life. Through his knowledge of anatomy and physiology and his ability to move Ch’i with his mind from years of martial arts training, he learned to walk again. He went on to be Principal Research Scientist, Head of Water Quality Laboratory Environmental Protection Authority of Victoria from 1985 to 1988.

During his period of recovery he sought alternative and complementary therapies to help him walk better, including massage, chiropractic, osteopathy, homeopathy, naturopathy, acupuncture, and even Filipino Faith Healing. Kinesiology, a form of direct muscle biofeedback, helped him the most. Completely fascinated by this technique, he spent the next five years learning everything he could about energy medicine. In 1988 he resigned from the EPA to take up this work full time. He spent time in the U.S. studying Applied Physiology, a physiologically based form of kinesiology, and upon his return to Australia in 1989 he opened an Applied Physiology clinic, Melbourne Applied Physiology, and was its Director from 1991 until his move to the Lydian Center in 2009.

Starting in 1985, Charles began working with clinical psychologists, speech pathologists, neurologists and other health professionals to develop the Learning Enhancement Acupressure Program (LEAP), a program for the correction of most learning problems. He researches, teaches and lectures internationally on LEAP, kinesiology, anatomy and physiology, and neurology.
