I study intensive agrarian systems and their sustainability through time. I focus on investigating their capacity to cope with socio-environmental shocks and manage uncertainty. My approach is holistic and merges anthropological frameworks with methods from the environmental sciences, ecology, modeling and statistics. 

At UiB, I was the PI of the EU-funded project SIZE, which aimed at assessing the risks and benefits of promoting "large" and "small" irrigation systems through dynamic models and uncertainty/sensitivity analysis. This project was coordinated by the University of Bergen and had Princeton University as a partner institution.

​I am used to working on water-related topics with a wide range of scientists from different fields, including engineers, hydrologists, archaeologists, mathematicians, ecologists and computer and environmental scientists. So if you are interested in collaborating, please drop a line!
