Navid Izady

Dr. Izady received his PhD in Management Science from Lancaster University Management School in 2010, following a BSc and an MSc in Industrial Engineering from Sharif University of Technology in IRAN. He was then offered a lectureship position at the University of Southampton, jointly at the School of Mathematical Sciences and Southampton Business School under the EPSRC LANCS Initiative, where he worked for five years before joining Cass in 2015.

Dr. Izady's research interests lie in stochastic modelling of service and manufacturing operations, in particular those relevant to healthcare. He has collaborated with a wide range of hospitals and healthcare organizations through supervision of sponsored MSc and PhD projects and undertaking consultancy projects. Dr. Izady has taught modules in operations management, stochastic modelling and simulation, healthcare modelling, mathematical modelling, and decision modelling and analysis to BSc, MSc and MBA students.

Research

My interest is in performance modelling and optimization of business processes involving uncertainty, in particular those observed in healthcare operations. Examples include optimal staffing of accident and emergency (A&E) departments, capacity and demand planning in outpatient clinics, and resource planning including beds and staff in critical care units.

Research Topics

• Optimal capacity and demand planning in networks of outpatient clinics
• Partial pooling of resources in hospital wards
• Integrated disease progression modelling and resource planning in healthcare
