Welcome! Here you can find information about my research, which is mainly concerned with modelling and quantifying severe uncertainty and decision making under severe uncertainty. My interests lie in the theoretical probabilistic foundations behind such modelling, as well as practical statistical applications of such modelling. In many practical applications, severe uncertainty arises due to insufficient data or expert opinion, relative to the complexity of the model, and one is compelled to work with partial probability specifications, such as probability bounds. My work focuses on the mathematical theory for propagating probability bounds through models and through decision problems. I also look at practical statistical applications of such theories, mostly in engineering and in environmental sciences.
