Research interests
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 and historical frameworks with methods from the environmental sciences, ecology, modeling and statistics, especially uncertainty and sensitivity analysis.
I am currently the PI of the EU-funded project SIZE, which aims at assessing the risks and benefits of promoting "large" and "small" irrigation systems through anthropological / historical perspectives, dynamic models and uncertainty/sensitivity analysis. This project is coordinated by the University of Bergen and has Princeton University as a partner institution. SIZE has received funding from the European Union's Horizon 2020 research and innovation program under the Marie Sklodowska-Curie grant agreement No 792178.
I am used to work on water-related topics with a wide range of scientists from different fields, including historians, engineers, hydrologists, archaeologists, mathematicians, ecologists and computer and environmental scientists. So if you are interested in collaborating, please drop a line!

ARE THE RESULTS OF THE GROUNDWATER MODEL ROBUST?
Despite groundwater models and water withdrawal projections being fraught with uncertainties, they are usually disregarded or assessed perfunctorily. This should cast a large shadow on the reliability of any modelling exercise. Here we briefly touch upon this topic through a criticism of the recent work by De Graaf et al., published in Nature.
CURRENT MODELS UNDERESTIMATE FUTURE IRRIGATED AREAS
By means of a systematic uncertainty and sensitivity analysis, we found that the potential extension of irrigation in 2050 might be much larger than previously thought, with serious implications for water management and environmental sustainability.
