SALLY BRAILSFORD is a Professor of Management Science at the University of Southampton, UK. She received a BSc in Mathematics from the University of London, and an MSc and PhD in Operational Research from the University of Southampton. Prior to her academic career, she worked as a nurse in the UK National Health Service. She has worked at the University of Southampton since the late 1980s, mainly using simulation approaches for a wide range of applications in healthcare. From 2010-19 she was Coordinator of the European Working Group on Operations Research Applied to Health Services (ORAHS), and in 2019 she ended a 7-year term of office as founding Editor-in-Chief of the international journal Health Systems. Her research interests include simulation modeling methodologies, in particular hybrid simulation (she was one of the instigators of the hybrid simulation track at WSC), and the modeling of human behavior in healthcare systems.
