Description of Research Expertise

Dr. Pack is pursuing research on genetics/genomics of sleep and its disorders. His laboratory is conducting studies in Drosophila and mice and translating these findings to humans. A particular focus of Dr. Pack’s work is to evaluate the genetic determinants of sleep homeostasis. Studies are ongoing to evaluate molecular mechanisms of sleepiness and sleep promotion using both hypothesis-driven and discovery science. The latter involves analysis of the changes in the transcription with sleep/wake and sleep deprivation in identified neuronal populations. Techniques being used include behavioral/sleep studies in Drosophila and mice, RT-PCR, Western analysis of protein, expression profiling, laser microcapture dissection, RNA seq and immunohistochemistry. Dr. Pack is committed to research training and directs two training grants from the National Institutes of Health.

Description of Clinical Expertise

Dr. Pack's clinical expertise is in sleep disorders with a particular focus on diagnosis and management of obstructive sleep apnea. He is internationally recognized for his expertise in this area and has been listed in the Best Doctor's in the United States and in the Philadelphia region (Philadelphia Magazine).
