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 Itmat Expertise

Major interest is in genomic/genetic approaches to sleep and its disorders. Studies to identify genetic risk factors for the common disorder sleep apnea and what determines the individual differences in response to sleep deprivation are in progress. These studies are being complemented by investigations to identify molecular signatures for sleep apnea and sleep deprivation. The approach being taken is to identify dynamic changes in expression of candidate genes and also expression profiling in circulating leukocytes and monocytes across the sleep period or with sleep deprivation.
