Martin Moore-Ede, M.D., Ph.D.
Chairman & Chief Executive Officer

For over 30 years, Dr. Martin Moore-Ede has been a leading expert on managing human performance and the risks of human fatigue in transportation and industrial businesses that operate 24/7. After experiencing the challenges of fatigue as a surgeon-in-training required to work 36-hour shifts, Dr. Moore-Ede was one of the first to define the challenges of living, working and sleeping in a 24 hour a day, 7-day a week world. As a professor at Harvard Medical School  (1975 – 1998), he led the team that located the biological clock in the human brain that controls the timing of sleep and wake, and pioneered research on how the human body can safely adapt to working around the clock and sustain optimum physical and mental performance.

In 1983 Dr. Moore-Ede founded CIRCADIAN®  (, a research and consulting firm dedicated to improving productivity, heatlh and safety in round-the-clcok operations, and reducing the costs and liabilities of managing a 24/7 workforce. As Chairman and CEO, he has guided the growth of the international network of CIRCADIAN companies which now advises over half of the Fortune 500 companies and many international companies on 24/7 work schedules and fatigue risk management. Dr. Moore-Ede founded Circadian ZircLight Inc. in 2011 to develop innovative LED lighting products that provide physiologically optimized light spectra across day and night based on comprehensive medical research and a proprietary IP portfolio. CIRCADIAN® Light products provide the energy-saving and technology advantages of LED lighting without the considerable downside risks of dosing large populations of people with blue wavelengths at night. CIRCADIAN ZircLight is a member of the international “CIRCADIAN®” group of companies, founded in 1983, which provides products and services to over half of the Fortune 500 companies for optimizing 24/7 workforce productivity, health and safety.

Dr. Moore-Ede graduated with a First Class Honors degree in Physiology from the University of London, and received his medical degrees from Guy’s Hospital Medical School, and his Ph.D. in Physiology from Harvard University. He has published 10 books, and more than 145 scientific papers on human fatigue, errors and accidents and the physiology of sleep deprivation and circadian rhythms. Dr. Moore-Ede holds multiple patents on tools for assessing and mitigating fatigue risk including the Circadian Alertness Simulator (CAS) a scientifically validated fatigue risk model and pending patent on ZircLight technologies. He has served on multiple national and international committees, and has received numerous awards including the Bowditch Lectureship of the American Physiological Society. He is a frequent guest on television (CNN, Today Show, Good Morning America, 20:20, Dateline, Oprah Winfrey Show, Nova, BBC), radio (NPR Fresh Air, Connection), and print media (Wall Street Journal, New York Times, Washington Post, Time and Newsweek). He has testified before Congressional committees on multiple occasions, and advised government agencies on hours of service and working time regulations in the US, Canada and the U.K.
