Arnaud Grignard is a computer scientist specializing in complex systems modeling, information visualization and agent-based model. He holds a PhD in Computer Science from Pierre and Marie Curie University. He is now a research scientist in the City Science research group at the MIT Media Lab under the supervision of Kent Larson. While working on different fields of application such as multi-level, urban systems and human mobility, he develops a new approach called agent-based visualization to handle real-time visualization tasks applied both to data and simulation outputs. Since 2011, Grignard is one of the main developers of the GAMA Platform , a modeling and simulation development environment for building spatially explicit, agent-based simulations. 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, TheCosmoCompany).

Arnaud is working on different projects, most of them related to the CityScope project , developed and deployed in the different cities of the CityScience Network through a multi-level interactive and tangible, agent-based visualization. He develops a novel methodology of interaction and collaboration embedded in the MIT CityScope framework , a data-driven platform that simulates the impacts of interventions on urban ecosystems prior to detail-design and execution.

This framework used for civic engagement, urban development, and decision making enables the creation of an artificial micro-world, which 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.
