Abstract: I will give an overview of my studies on collective decision making in distributed systems of the last ten years. Such systems, found in biology, sociology, and engineering, are composed of a large number of interacting individuals that coordinate in order to reach a consensus. The main phases of the collective decision making process consist of identifying the available options, estimating their quality, and selecting the best option or any of them. I will present the main results of my research in understanding and designing each of these phases. Collective systems are inherently difficult to analyse as the stochastic nonlinear interactions between individuals can give rise to complex emergent dynamics. Therefore, I employ a collection of advanced techniques, commonly defined as multiscale modelling. Relying on a set of methods, rather than a single one, gives the benefit of having complementary techniques addressing one another's limitations. In fact, through multiscale modelling, it is possible to analyse the systems at various levels of complexity and detail, from macroscopic group-level dynamics to microscopic individual-level behaviour, and from noise-free deterministic models to stochastic spatial descriptions. I finally shed a light on the recently developed opensource software for automated multiscale modelling.

Bio: Dr Andreagiovanni Reina is a Research Fellow of the Belgian FNRS in Collective Behaviour at the Institute for Interdisciplinary Studies on Artificial Intelligence (IRIDIA) of the Université Libre de Bruxelles, Belgium. He is currently working on modelling heterogeneity in decentralised consensus. He has been a Research Fellow at the University of Sheffield (UK) from 2015 to 2020. He holds a PhD in Applied Sciences from IRIDIA, Université Libre de Bruxelles, and an MSc in Computer Engineering from Politecnico di Milano, Italy. He has been a researcher in six European projects on distributed robotic systems since 2009.
