Dr. Martin Scharf, PhD, FABSM 
Sub-Investigator, Research & Development Consultant

Dr Martin Scharf started his career in sleep research at UCLA, where he became the Associate Director of arguably the first Sleep Disorders Center in the U.S., under the direction of Dr Anthony Kales, a pioneer in the field of Sleep Medicine. He received his PhD from the Pennsylvania State University in Hershey and has been involved with the development and clinical testing of virtually every major pharmaceutical used in treating disorders of sleep and wakefulness, resulting in over 250 scientific papers. In 1983, he introduced Gamma Hydroxybutyrate (Xyrem) into the U.S. for the treatment of narcolepsy with cataplexy and contributed over 800 patient/years of safety data towards FDA approval. His testimony before the Congress resulted in the bifurcated scheduling of the drug for Narcolepsy. He has also served as an expert witness in cases involving sleep disorders.

Dr Scharf created and directed the first free-standing sleep disorders clinic in the US (Tristate Sleep Disorders Center) as well as this country's first sleep clinic satellite network. His satellite network resulted in the accreditation of almost twenty new sleep centers throughout the country.
Dr Scharf created one of the first schools for sleep laboratory technicians. A number of current and past leaders in the registered technician area were trained at his school and went on to shape the main sleep organization for sleep laboratory technicians.

Dr Scharf’s Research focus has centered around characterizing the effects and effectiveness of virtually every hypnotic marketed during the last forty years. His work in fibromyalgia has resulted in the first demonstrated pharmacological reduction in alpha intrusion into sleep (non-restorative Sleep) associated with improved patient symptoms and led to the current theory of positive allosteric modulation of GABAB compounds as possible treatments for the condition. Dr Scharf authored over 250 scientific papers

While serving as the Sleep Consultant to the infant apnea team at Children’s Hospital in Cincinnati, he tested the breath rite nasal strip in infants demonstrating a reduction in apnea events in newborns with colds when wearing the strip. Scharf also developed a system for treating bed wetting which was detailed in his book "Waking Up Dry: How to End Bedwetting Forever”. His work in bedwetting has been featured on national television shows such as 20/20 and again on the tenth anniversary highlighting the decades Best of 20/20. Dr Scharf has appeared as a guest on such shows as Today, Good Morning America and Oprah. Dr Scharf left Tristate Sleep Disorders Center to join with Dr Ahmed in 2013.
