Research Interests

James's primary interest is in the use of CEA evidence by policy makers. He is interested in the understanding of CEA metrics by decision makers and the influence of these measures on policy choices. He is interested in the factors that might influence decision makers to recommend adoption that are not formally accounted for in cost-effectiveness metrics. He is also interested in the interpretation of uncertainty estimates such as CEACs and EVPI by decision makers.

His other primary area of interest is in CEA model construction and specification. James is interested in the fit of models to the policy choices they are to inform, including how well do models account for patient heterogeneity and how do they cope with parameters that change over time.

His interest in time in CEA modelling relates in part to his work on discounting. James' is interested in the role discounting plays in CEA models, especially when differential discounting is used. The use of differential discounting adds a dynamic aspect to models as the valuation of health implicitly changes over time.
