Editor-in-Chief: Professor Ahmed S. BaHammam

Ahmed S. BaHammam is the Director of the University Sleep Medicine Research Center and Sleep Medicine Fellowship Program, King Saud University, and Professor of Sleep Medicine at the College of Medicine, King Saud University.
Prof. BaHammam did his specialization in Pulmonary Medicine, Critical Care Medicine, and Sleep Medicine at the University of Manitoba, Canada, in the mid-1990s with Meir Kryger. He also obtained the Royal College of Physicians of London and the American College of Physicians' Fellowships. He was awarded the Lifetime Achievement Award of King Saud University in 2016.
Prof. BaHammam has experience with medical journal editorship for over 17 years, as Editor-in-Chief, Associate Editor, or a member of the Editorial Board of several general and specialty medical journals, and a reviewer of the top specialty journals. He was nominated to the Sleep & Respiratory Neurobiology Planning Committee (SRN) membership of the American Thoracic Society in 2018 and is a founding member of the Asian Society of Sleep Medicine (ASSM).
Professor BaHammam's research focuses on several sleep-related topics, including obesity hypoventilation syndrome, central hypersomnolence disorders, and the impact of intermittent fasting and mealtime on sleep and circadian rhythm. He has received several grants for his research. He authored more than 300 peer-review articles and book chapters, and two books in the field of sleep medicine and sleep research.

Dr Appleton

Associate Editor: Sarah Appleton

Dr Sarah Appleton, BSc (Hons), PhD, is a chronic disease epidemiologist and Senior Research fellow at AISH at Flinders University, South Australia. Prior to this she was working in The Health Observatory, Adelaide Medical School, The University of Adelaide. She completed her PhD there in 2010 after working across a broad range of laboratory-based basic science and clinical research areas. She is a Chief Investigator for the North West Adelaide Health Study (NWAHS), a biomedical cohort study established in 2000-01. Since 2012, she has made contributions to identifying the burden of undiagnosed obstructive sleep apnea in men and its relationship with chronic disease outcomes life in the Men Androgens Inflammation Lifestyle Environment and Stress (MAILES) study. She coordinated the follow-up of the MAILES study cohort in 2018-19 including a repeat full-in home sleep studies and assessments of cardiometabolic factors and cognition. Her work has led to over 100 original publications in chronic disease and sleep epidemiology.
Sarah’s research has aimed to identify clinical phenotypes of people at risk of poor health outcomes in order to inform evidenced based policy for the improved delivery of health services and prevention of chronic disease. She has a particular interest in the role of gender in the diagnosis and management of sleep disorders, particularly sleep apnea.

Professor Wright

Associate Editor: Kenneth P. Wright Jr. , PhD.

Ken Wright is Professor in the Department of Integrative Physiology, Director of the Sleep and Chronobiology Laboratory, and member Center for Neuroscience at the University of Colorado Boulder. He is also Adjunct Professor of Medicine in the Division of Endocrinology, Metabolism & Diabetes and member Nutrition and Obesity Research Center at the University of Colorado Anschutz Medical Campus.

Dr. Wright received his BS in Psychology from the University of Arizona and began his career in sleep under the direction of Richard R. Bootzin, PhD. He received his MA and PhD in Behavioral Neuroscience and a postdoc in Sleep and Circadian Rhythms from Bowling Green State University under the direction of Pietro Badia PhD. He then completed a postdoctoral fellowship in Sleep and Circadian Medicine in the Division of Sleep Medicine at Harvard Medical School and Brigham and Women’s Hospital under the Direction of Charles A. Czeisler PhD, MD.  He served on the Faculty at Harvard Medical School prior to joining the Faculty at the University of Colorado in 2002.  He serves as chair of the program committee for the Associated Professional Sleep Societies (APSS). He has chaired the circadian rhythms section of the Sleep Research Society (SRS), the trainee professional development day for the Society for Research on Biological Rhythms and has served as a member of the SRS presidential task forces. He has served on the American Academy of Sleep Medicine (AASM) task force on the evaluation and treatment of circadian rhythm sleep disorders, was a member of the AASM Circadian Rhythm Disorders workgroup for the International Classification of Sleep Disorders Revision 3 (ICSD-3), was editor of the SRS bulletin and the Trainee Manual in Sleep Research for the APSS, and was co-chair for the World Federation Sleep Research and Sleep Medicine Societies Trainee Development Day. He currently serves as a member of the National Institutes of Health – National Heart, Lung and Blood Institute Sleep Disorders Research Advisory Board. Dr. Wright has served as a reviewer for numerous national and international grant agencies; he serves as a consultant for government agencies, universities and industry, and as a reviewer for numerous journals. He has published over 80 original articles and reviews and was guest editor for a special issue of Sleep Medicine Clinics: Basics of Circadian Biology and Circadian Rhythm Sleep Disorders.

Dr. Wright’s research is aimed at explaining the physiology of sleep and circadian timing in humans, understanding the health and safety consequences of sleep and circadian disruption, such as obesity and impaired cognition, and applying that knowledge to improve public health and safety. His research is also aimed at developing strategies to promote sleep, wakefulness, and health due to insufficient sleep and circadian rhythm sleep-wake disorders.
