With an early training in engineering and environmental sciences, my interdisciplinary research combines technical knowledge with various theoretical concepts and empirical methods from the natural and social sciences. My intellectual goal is to better understand the multi-scale processes that control the behavior of complex socio-technical systems, in particular (nuclear) energy technologies, in their relation with society.
My current research deals with issues related to the radioactive waste materials produced at commercial and military facilities in a context of uncertain energy transitions and persisting social concerns over nuclear energy technologies. It covers the theoretical, methodological and empirical aspects of the back-end of the nuclear fuel cycle integrating knowledge from various disciplines in the science, engineering and social sciences areas.
This research program has three main components.
Uncertainty analysis of geological repositories
This technical component covers the following questions: How to quantify uncertainty in the safety assessment of geological repository systems? What methods and models can be used, and how?
Fields involved: nuclear materials, earth sciences, and uncertainty modelling.
Safety case for the assessment of geological repositories
This science-policy component covers the following questions: When to quantify uncertainty in the safety assessment of geological repository systems? When not to? What rules should be considered in the safety case of geological repositories? How to account for expert and non-expert judgement?
Fields involved: sensitivity analysis, sensitivity auditing, and science and technology studies (STS).
Integrated analysis of geological repositories
This other technical component covers the following questions: What are the biophysical “costs” of geological repository systems in relation to energy transitions? Can countries dispose in geological repositories all of their spent fuels and high-level waste before the end of this century? How are national programs for nuclear waste disposal affecting and affected by energy policies?
Fields involved: multi-scale integrated analysis, energy analysis, and environmental sciences.
