Dr. Allan I. Pack is the John Miclot Professor of Medicine, Director of the Center for Sleep and Circadian Neurobiology and Chief of the Division of Sleep Medicine at the University of Pennsylvania (Penn).  He graduated from medical school in Glasgow and worked at the Royal Infirmary in Glasgow before relocating to the United States.  He has been on the faculty at the University of Pennsylvania since 1976.  He directed an NIH-funded Specialized Center of Research on sleep apnea from 1988 to 2008.  He directs two Center grants—“The Mechanisms of Alterations in Sleep with Age” and “Individual Differences in Obstructive Sleep Apnea”.  He is the Founding Director of the Center for Sleep and Circadian Neurobiology and the Division of Sleep Medicine.  These are the first multidisciplinary independent sleep research and clinical sleep medicine programs to be established at any medical school in the United States.  Dr. Pack’s current main area of focus is on functional genomic approaches to sleep and its disorders.  He uses both Drosophila and mouse models in his work and translates findings to humans.  A major component of his research relates to the pathogenesis and consequences of the common disorder, obstructive sleep apnea, and to the effects of sleep loss.  Dr. Pack is actively pursuing research to establish the functions of sleep both for brain and peripheral organs.  He is engaged in identifying biomarkers for sleep loss and obstructive sleep apnea.  Research training is also a major commitment of Dr. Pack.  He has received a number of awards for his activities including the Nathaniel Kleitman Lifetime Achievement Award and the William C. Dement Academic Achievement Award from the American Academy of Sleep Medicine, the Lifetime Achievement Award from the National Sleep Foundation, and the Farrell Prize in Sleep Medicine from Harvard Medical School.
