Post Doctoral Fellows
Takashi Abe, Ph.D.
Postdoctoral Fellow for the Unit for Experimental Psychiatry
University of Pennsylvania Perelman School of Medicine
Takashi Abe, Ph.D. is a Post Doctoral Fellow in the Division of Sleep and Chronobiology, Department of Psychiatory, University of Pennsylvania Perelman School of Medicine. Dr. Abe received his B.S., M.S., and Ph.D. in Psychophysiology from Hiroshima University. As a graduate student, he researched about brain activity during human REM sleep by using the methods of electroencephalography (EEG) including power spectral analysis and event-related potential, and functional magnetic resonance imaging with simultaneous EEG recording. In addition, he studied about functional significance of post-learning sleep on advantageous decision-making. As a postdoctoral fellow at Japan Somnology Center, Neuropsychiatric Research Institute, Dr. Abe studied epidemiological study about sleepiness-related motor vehicle accidents, effects of disturbed sleep and sleep deprivation on cognitive functions, and the method for evaluating deteriorated vigilance using ocular measurements. Dr. Abe joined the Division of Sleep and Chronobiology to pursue his research interests in the effect of sleep loss on neurobehavioral functions and sleep physiology as well as the methods to evaluate sleepiness and fatigue based on slow eyelid closure (PERCLOS).
Dr. Abe was awarded Young Scientist Award Creative Research Award of The 15th World Congress of the International Society of Brain Electromagnetic Topography in 2004, Excellent Student Scholar Award of Hiroshima University in 2005, 14th Encouraging Prize of Japanese Society of Sleep Research in 2009, and Research Award of Mitsui Sumitomo Insurance Welfare Foundation in 2011, and 17th Encouraging Prize of Japanese Society of Sleep Research in 2012.
