The Center for Automation Technologies and Systems (CATS), together with the Smart Lighting Engineering Research Center (ERC) and the Department of Electrical, Computer & Systems Engineering (ECSE), present a seminar by Dr. David Thorsley, Research Scientist, DoD Biotechnology HPC Software Applications Institute (BHSAI) at Fort Detrick in Frederick, MD, entitled: "Mathematical Modeling for Stress and Fatigue Management," to be held in JEC 3117 on Friday, April 13 at 11:00am. Everyone is welcome!!
The demands of the theater require warfighters to experience irregular or disturbed sleep schedules. Accumulation of sleep debt leads to fatigue, which in turn is associated with degraded cognitive performance and increased risk-taking, thereby causing serious accidents. Furthermore, sleep debt is a factor affecting performance of the stress response system and may be an exacerbating factor in the etiology of psychological disorders such as PTSD and depression.
This talk will describe efforts to mathematically model the effects of total sleep deprivation and chronic sleep restriction on cognitive performance, as measured by the psychomotor vigilance task, and on hypothalamo-pituitary-adrenal axis activity, as measured by the stress hormone cortisol. Our group's research focuses on model individualization to determine whether particular individuals are resilient or vulnerable to fatigue and stress. By using our models to help determine the physiological bases of resilience, we aim to decrease the number of casualties incurred as a result of fatigue.
The projects described in this talk are joint work with the Walter Reed Institute of Army Research and the University of Chicago.
David Thorsley earned his Ph.D. in Electrical Engineering: Systems from the University of Michigan in 2006. From 2006-2010, he was a postdoctoral research in the Department of Electrical Engineering at the University of Washington, Seattle. Currently, he is a Research Scientist at the DoD Biotechnology HPC Software Applications Institute (BHSAI) located at Fort Detrick in Frederick, Maryland. His research interests lie at the interconnection between systems theory and biology and include physiological modeling and signal processing, systems and synthetic biology, and discrete stochastic processes and stochastic biochemical systems.
