Public Engagement with Research Case Studies

MSc, PhD

Job Title:

Professor of Management Science; Director of Research Centre

Affiliated Research Division:

Centre for Healthcare Innovation & Improvement (CHI2)


Information, Decisions and Operations

Key Research Interests:

Application of operational research / management science to health care, computer modelling and simulation, health care analytics.

Research Interests

I am an academic researcher that conducts analytical rigorous but highly applied research that generates both academic and practical impact. Working in close collaboration with clinicians and healthcare professionals I develop and apply rigorous methods to help better plan and deliver care services. I am also interested in the evaluation of the likely impact of healthcare interventions and policy initiatives using mathematical modelling and computer simulation. I have worked on a large number of problems in health and care ranging from the monitoring of surgical site infections to the organisation of care services such as stroke prevention, glaucoma, mental health and others.

PhD Supervision

I welcome enquiries from potential PhD students in the areas of operational research / management science applied to health care problems and in systems modelling and simulation.
