Dr. Charlene Gamaldo is the medical director of the Johns Hopkins Center for Sleep at Howard County General Hospital. Her research interests are in the area of sleep medicine, specifically investigating the co-morbid health consequences of chronic sleep deprivation.
Dr. Gamaldo received her bachelors degree from the University of Virginia in Charlottesville. She then earned her medical degree from The George Washington University School of Medicine and completed an internship at the Greater Baltimore Medical Center. After her neurology residency at the University of North Carolina Hospital, Dr. Gamaldo became the first neurology clinical sleep research fellow at Johns Hopkins, where she served as a co-investigator on several studies evaluating the pathophysiology of restless legs syndrome (RLS).

Research & Publications
Dr. Gamaldo's research interests include studying the impact of sleep on manifestation and progression of neurological diseases. Looking at this relationship between sleep and disease progression in HIV will serve as the foundation for future work focused on the impact of sleep loss on other aspects of neurobiological function. By conducting this research, it is serving as a model for sleep research using the efforts of a diverse group of interdisciplinary collaborators and as a result has led to ongoing and evolving research projects that now include a growing list of collaborators (Neurology, OB/Gyn, Psychiatry, Urology, School of Nursing and Public Health along with the National Institute on Aging). The results of this study are suggesting that compromised sleep quality and duration may have a significant impact on cognitive performance in HIV+ individuals. Learn more about this study.
