Dr Nav Mustafee

Dr Nav Mustafee is the founding co-chair of the IMPACT Network. He is Senior Lecturer in Operations Management at University of Exeter Business School and an Honorary Researcher at Torbay & South Devon NHS Foundation Trust. His research interests are in Hybrid Systems Modelling (including Hybrid Simulation), Health & Social Care Modelling and Simulation (M&S), and Bibliometric analysis of knowledge domains. Previously, Nav worked in Swansea University and collaborated on healthcare studies with Morriston and Singleton hospitals (Abertawe Bro Morgannwg University Health Board). Nav has organised the Health and Social Care stream for the UK Operational Research Society’s 2016 and 2017 Annual Conferences (OR58 – Plymouth; OR59 – Loughborough).

Nav is an Associate Editor of Simulation: The Transactions of the Society for Modeling & Simulation International, the Journal of Simulation and the ACM Special Interest Group on Simulation and Modeling (SIGSIM) M&S Knowledge Repository. He has guest-edited several special issues, including two special issues on healthcare M&S, for journals such as the ACM Transactions on Modelling and Computer Simulation (TOMACS), Concurrency and Computation: Practice and Experience (CCPE), Simulation: Transactions of the SCS, Journal of Simulation and Journal of Enterprise Information Management. Nav has served the M&S research community by undertaking leadership roles in all the leading M&S conferences, including, the Winter Simulation Conference (as Track Chair for Hybrid Simulation: 2014-2017, Proceedings Co-editor for WSC 2017), Spring Simulation Multi-Conference (Awards chair – 2017, General Chair – 2016, Vice-General Chair – 2015, Program Chair – 2014) and ACM SIGSIM PADS Conference (Program Co-Chair & Proceedings Co-Editor, 2015).

Prof. John Powell

Prof. John Powell is Professor of Strategy at University of Exeter Business School. John has contributed to the development of the health and social care modelling agenda at the Business School, and together with Dr. Nav Mustafee and Dr. Andrew Fordyce, this has led to the development of the IMPACT network. John’s research interests are in the area of soft systems with particular application to the behaviour of knowledge in strategic situations. He has published extensively in the international literature on systems behaviour particularly in respect of critical human activity systems or CHASs. Health systems are included in this category; they cannot be represented by appeal only to a single, observable reality, since the human components will create valuations and system ‘realities’ specific to themselves and their context.


Prof. Andi Smart

Prof. Andi Smart is Professor of Operations and Process Management at University of Exeter Business School. Before joining Exeter he completed a degree in Computing and Informatics and a PhD in Operations Management. At Exeter, he is the Director of the Centre for Innovation and Service Research (ISR), and the Director of the Organisations in Transition (OiT) Research Cluster. Andi has held a number of positions with professional bodies including: Co-Editor of the International Journal of Operations and Production Management; Board Member of the European Operations Management Association (EurOMA). He is also the Founder of the EurOMA Service Operations Management Forum. His research interests are in the design and improvement of operations systems. His postdoctoral work, which commenced in 1996, has involved addressing design and improvement research problems in a wide variety of sectors (Manufacturing, Financial Services, Telecommunications, Energy, Police Service, Cultural Heritage, Logistics, Information Systems, Health). His work in Healthcare has included projects with: the Royal Devon and Exeter NHS Foundation Trust (where he holds a Research Fellow Honorary Contract); Torbay and South Devon NHS Foundation Trust; North Devon Healthcare NHS Trust; Western Sussex Hospitals NHS Foundation Trust; Patient Opinion; South West GP practices. These projects have included: Systems Models of admission to discharge; Discrete Event Simulation modelling of Accident and Emergency focusing on ‘Fast Track’ Strategies; Bed Capacity Analyses using simulation and Design of Experiment (DoE) approaches; Patient Experience analyses using TextAnalytics; Predictive workforce modelling in General Practice. He has supervised PhD students on Patient Safety and Resilience, and Enhanced Recovery in Medicine.


Alison Harper is undertaking her PhD at the University of Exeter Business School with a focus on the hybrid application of predictive analytics with simulation to support healthcare operational decision-making.  Alison is a chartered Physiotherapist and an accredited Ergonomist, with an MSc in Healthcare Human Factors and an MRes in Management.  As well as working extensively in healthcare in both clinical roles and in service development, she has delivered successful research projects at Royal Devon & Exeter NHS FT and South Devon and Torbay NHS FT.  Her primary interest is in applied research that makes a real difference to NHS services and ultimately to patient care.
