Research interests

With my research I aim to contribute to better decision making in environmental and conservation management. For this I combine methods and insights from multiple disciplines, including decision science, data science, operations research, ecological modelling, and economics.
Research interests:
- Decision analysis, integrated assessment, and management strategy evaluation
- Uncertainty, sensitivity, and the value of information in modelling and management
- (Bayesian) statistical modelling
- Developing tools and software

Master thesis projects
