Panagiotis Matsangas

Phone: (831) 656-3481


Dr. Matsangas was a Naval Officer in the Hellenic Navy for 25 years. He received his Ph.D. in Modeling and Simulation and M.Sc. in Operations Research from the Naval Postgraduate School.<br> Since 2004, he has been involved with human performance research focusing on operational environments, and participated in projects for the Department of the Navy, Office of Naval Research, the Naval Surface Warfare Center, and the Naval Advanced Medical Development (NAMD) Program Office. Dr. Matsangas’ research interests are in the area of mathematical modelling of human behaviour with emphasis in the military and the naval operational environments, i.e., human performance modelling, motion sickness, sopite syndrome, watch schedule optimization, and the impact of sleep deprivation/ fatigue on performance.
