On December 9th, 2025, Arthur Brugière successfully defended his PhD thesis entitled “Dynamic Coupling and Scaling of Complex Socio-Environmental Models” (Couplage dynamique et passage à l’échelle de modèles socio-environnementaux complexes) at Thuyloi University, Hanoi.
The PhD defense was supervised by Dr. Alexis Drogoul (Research Director, UMMISCO, IRD) and Prof. Nguyen Ngoc Doanh (UMMISCO, VinUniversity).
About the PhD Thesis
Arthur Brugière’s doctoral research addresses one of the major methodological challenges in modeling complex socio-environmental systems: how to dynamically couple models that operate at multiple spatial and temporal scales. While multi-level agent-based models (ML-ABM) offer an appropriate paradigm, their practical implementation faces methodological challenges concerning the coordination and synchronization of heterogeneous levels and the dynamic transitions between their scales.
The contribution of this thesis articulates around two components: a framework of formalized constraints that ensure the coherence of inter-level interactions, and an automated spatio-temporal coordination system. The implementation takes the form of an extension to the GAMA platform (http://gama-platform.org), which offers an intuitive declarative syntax that masks technical complexity while preserving the expressiveness.
Arthur Brugière’s work represents a significant step forward in the modeling of complex socio-environmental systems. By making multi-level modeling more coherent, flexible, and accessible within GAMA, this research opens new perspectives for large-scale simulations in domains such as public health, risk management, and environmental education.

Since 2021, Arthur Brugière has been pursuing his PhD at the ACROSS Laboratory under the supervision of Dr. Alexis Drogoul and Prof. Nguyen Ngoc Doanh. His doctoral research is firmly embedded within ACROSS’s scientific activities, drawing on agent-based models, including COMOKIT (epidemiological modeling), and SIMPLE (environmental education), all of which were designed, developed, and implemented on the GAMA Platform (link) at the ACROSS Laboratory.
