Health economics

Health economics is concerned with assessing the cost-effectiveness of medical technologies. Computer models are often used to make cost-effectiveness estimates, and my main interest is in analysing uncertainty in cost-effectiveness model predictions. Other interests include eliciting utilities for different states of health, in particular the design and analysis of discrete choice surveys. I collaborate with researchers in ScHARR through the Centre for Bayesian Statistics in Health Economics.
