Arnaud Grignard is a computer scientist specializing in complex systems modeling and information visualization. He received his PhD in Computer Science from l'université Pierre et Marie Curie-UPMC in 2015 where he co-developed  a novel approach to agent-based simulation that handles real-time visualization tasks applied both to data and simulation outputs.

Since 2016, Grignard has been a research scientist in the City Science group at the MIT Media Lab working on multiple applications of agent-based modeling theory using evidence-based or data-driven simulations. He is involved with several collaboration within the CityScience Network that include urban land-use modeling, and mobility and hydraulic simulations. In addition, he is one of the main developers of the open source community surrounding the CityScience group.  

In 2021, he received a Marie Curie Fellowship and joined the Université de Lyon  in the LIRIS laboratory to apply his research on Reactive Agent-based Tangible simulation for decision making in urban studies (ReAgent).

Arnaud Grignard is a computer scientist specializing in complex systems modeling and information visualization. He received his PhD in Computer Science from l'université Pierre et Marie Curie-UPMC in 2015 where he co-developed  a novel approach to agent-based simulation that handles real-time visualization tasks applied both to data and simulation outputs.

Since 2016, Grignard has been a research scientist in the City Science group at the MIT Media Lab working on multiple applications of agent-based modeling theory using evidence-based or data-driven simulations. He is involved with several collaboration within the CityScience Network that include urban land-use modeling, and mobility and hydraulic simulations. In addition, he is one of the main developers of the open source community surrounding the CityScience group.  

In 2021, he received a Marie Curie Fellowship and joined the Université de Lyon  in the LIRIS laboratory to apply his research on Reactive Agent-based Tangible simulation for decision making in urban studies (ReAgent). 

Grignard is working on different projects, most that related to the CityScope platform, which has been deployed in the more than 20 cities around the world that makeup the CityScience Network. The CityScope platform is a tangible, interactive urban simulation tool the incorporates agent-based visualization for decision making. His work and research is looking at a novel methodology of interaction and collaboration for CityScope, a data-driven simulation platform to support the understanding of interventions on urban ecosystems prior throughout the design and execution process. 

His  research has been applied  in many different contexts, namely university research laboratories (MIT Media Lab, CNRS, ENS Lyon, UPMC), public health research departments (IRD, UNDP, Pasteur Institute), and within IT companies (Philips Research, Boston Consulting Group, Bouygues, Wanxiang).

Since 2011, Grignard has been one of the principal developers of the GAMA Platform, an agent-based modeling environment for the generation of spatially explicit simulations. During his PhD, he spent 3 years in Hanoi, Vietnam at IRD/UMMISCO working in close collaboration with the Gama Platform team to develop agent-based visualization tools.

His research is used for civic engagement, urban development, and decision making enables the creation of an artificial micro-world and allows the modeler to create and modify new urban scenarios in an iterative and dynamic evidence-based process. This not only helps to better understand the impact of new policies on a city, but also fosters a better-informed discussion of different futures.
