My research focuses on the development and application of state-of-the-art modelling approaches to provide robust and defensible decision-making support for real-world resource management problems.
My work combines data assimilation, uncertainty assessment and optimisation under uncertainty approaches with process-based environmental models. For example, I have applied hydrological models that simulate advective-dispersive-reactive contaminant transport to identify optimal land-use management strategies (i.e., by maximising farm production while satisfying ecological river health conditions).
A particular interest of mine is improving the efficiency and scalability of the decision-support modelling approaches such that they are applicable to complex and high dimensional problems. I am also interested in model emulation and data-driven methods; however, most problems that I have encountered to date have been ill-posed (i.e., there are insufficient data to inform the many model dimensions needed to adequately characterise uncertainty).
