David is a practitioner with over 15 years experience with the Government Operational Research Service (GORS) and is currently working for NHS England. He specialises in applying OR techniques, such as simulation, to improving productivity, performance and user experience in a range of healthcare settings.
Prior to this he taught at undergraduate and postgraduate level at Sheffield Hallam University Business School. He has maintained his teaching role while working for the NHS, tutoring on a distance learning MBA and running introductory courses for the Operational Research Society.
He is a frequent contributor to the Operational Research Society and Government Operational Research Service conferences, specialising in passing on how to undertake and communicate analysis for impact in a policy setting.
Like many operational researchers he started his career as a scientist, training as a medical physicist. But as his career has developed he has enjoyed developing other skills. He has recently completed a course at the Northern Film School learning how to write and direct for the cinema. Skills which he hopes will enhance his role as an operational researcher.
David’s main research interest in the past 10 years is in developing modelling techniques which can be applied to support investment cases which meet Treasury Green Book standards. He frequently uses simulation to forecast the value for money case where retrospective evidence is lacking.
The majority of applications of his work involve the boundary between complicated and complex systems which test the limit of many of the traditional OR techniques.
This requires the development of both soft and hard OR methods to able move a problem from inception to delivery.
