Biophysical modelling of agricultural and energy systems
I develop and use flow-based models to study how the material structure of systems shapes their performance, vulnerabilities, historical trajectories and possible futures. My PhD focuses on French agricultural metabolism from 1852 to 2050.

Selected work
Flow-based models for systems in transition
My work makes physical constraints, dependencies and trade-offs explicit in complex socio-ecological systems.
Vulnerabilities & historical trajectories
Crop–livestock composition, agro-environmental performance, inductive typologies and path dependence over the long run.
ProjectComparing visions for French agriculture
Biophysical harmonisation of contrasted scenarios to make their assumptions and trade-offs comparable.
ProjectEU energy dependence
Development of a multisectoral model of energy dependence across the 27 EU Member States.
Ongoing workThe Shift Project
From research to public expertise
At The Shift Project, I have worked on the Agriculture project, the Plan robuste pour l'économie française (PREF) and food-system work. I now work mainly on energy sovereignty within the public affairs team.
