About me


Me

I'm a Postdoctoral Research Associate at the Beyond Center for Fundamental Concepts in Science, Arizona State University. I'm affiliated with the School of Earth and Space Exploration but you will normally find me in the School of Life Sciences at the Social Insect Research Group. Here at ASU, I'm studying information processes that originate when colonies of ants Temnothorax rugatulus make collective decisions. My studies are supervised by Prof. Sara Walker, Prof. Ted Pavlic, and Prof. Stephen Pratt.

Computer Engineer by formation, I've a background in artificial intelligence and robotics with a focus on agent-based modeling. I received a PhD in Sciences of Technologies and Engineering at Université Libre de Bruxelles (2016) under the supervision of Prof. Marco Dorigo and Prof. Heiko Hamann, and MSc (cum laude) and BSc degrees in Engineering of Computing Systems at Politecnico di Milano (2011 and 2008).

My research interests span over scientific disciplines as diverse as Robotics, Biology, and Physics. I focus on the study of self-organized collective decision-making processes both in living and artificial collectives. So far, most of my studies concentrated on the modeling and design of control strategies for robot swarms while, more recently, I broaden my focus to the study of collective decisions in ant colonies (Temnothorax rugatulus) as well as in slime molds (Physarum polycephalum). While my primary research objective is to deepen the understanding of the complex, self-organized processes leading a group to a collective decision, I have a broad interest in emerging collective phenomena as well as in the development of machine learning applications for biology.

Collective decisions in robot swarms


This project focuses on the design and mathematical analysis of collective decision-making strategies for swarms of autonomous robots. In a robot swarm, the cognitive abilities of individual robots may prove too limited with respect to the complexity of the problem at hand; yet, by cooperating with each other, the robots in a swarm can overcome their cognitive limitations by aggregating information at the collective level obtaining superior collective decisions. In this project, we investigate the development of a modular and model-driven methodology to design collective decision-making strategies for the best-of-n problem, that is, the problem of finding the best among a finite set of options. We put forward a methodology supported by a macroscopic mathematical framework that allows designers to study the dynamics of a swarm across different levels of abstraction: from mean field approximations that allow for the study of the asymptotic properties of a strategies, to stochastic mathematical models that account for finite-size effects in swarms with finite number of robots.

The Kilogrid project


Me

The Kilogrid is an open-hardware virtualization environment and data logging manager for the Kilobot robot. The Kilogrid is designed to extend the sensory-motor abilities of the Kilobot robot, to simplify the task of collecting data during experiments, and to provide researchers with a tool to fine-control the parameters of the experimental setup. Based on the design of the Kilobot robot and compatible with existing hardware, the Kilogrid is a modular system composed of a grid of computing nodes, or modules, that provides a bidirectional communication channel between the Kilobots and a remote workstation. In the videos below you can observe several demo experiments that showcase the implementation of virtual sensors, virtual actuators, and data logging.
