Andrea Baronchelli

Professor of Complexity Science at City, University of London,

Token Economy theme lead at The Alan Turing Institute,

Research Associate at the UCL Centre for Blockchain Technologies.

I investigate the dynamics of decentralised socio-technical systems using concepts and tools from the physics of complex systems, network science and data science.

Topics I research include the emergence and dynamics of social norms and shared category systems, tipping points in collective behaviour, polarisation in social networks, blockchain & crypto ecosystems, and human mobility.

My work has has been supported by public and private institutions (UKRI, ESRC, InnovateUK, UK Govt., PayPal, etc). In 2019, I received the Young Scientist Award for Socio and Econophysics from the German Physical Society.

Besides academia, I regularly help start-ups and companies in the blockchain/crypto space improve their products by assessing, and anticipating, the behaviour of the communities they aim to reach.

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.
