Andrea Baronchelli
I am a Professor of Complexity Science at City, University of London, and also the Token Economy theme lead at The Alan Turing Institute and a Research Associate at the UCL Centre for Blockchain Technologies.
I investigate how people behave and organize themselves in decentralized socio-technical systems. I use complex systems, network science, and machine learning to analyze large datasets, develop mathematical models, and run experiments with human subjects.
My work helps explain how people coordinate in social networks, interact with and shape blockchain technology, and how information spreads and creates polarization. I have also extensively investigated, and continue to research, the evolution of social norms, how we categorize the world, and what triggers tipping points in collective behavior. Additionally, I have explored human mobility and fundamental network science concepts like diffusion processes and the dynamics of time-varying networks.
My work has been published in top journals like Nature, Science, PNAS, Nature Human Behaviour, Nature Climate Change, Nature Communications, Science Advances, and Physical Review Letters. It has received support from various organizations, including UKRI, PayPal, ESRC, InnovateUK, and the UK Government. In 2019, I received the Young Scientist Award for Socio and Econophysics from the German Physical Society.
Mapping the NFT revolution
The paper Mapping the NFT revolution: market trends, trade networks, and visual features (Oct '21) presented the first comprehensive analysis of the NFT phenomenon.
Critical mass and tipping points in social convention
I have been researching the dynamics of norm formation and collective behaviour change for more than 15 years.
