Complex networks

The physics of higher-order interactions in complex systems

Complex networks have become the main paradigm for modelling the dynamics of interacting systems. However, networks are intrinsically limited to describing pairwise interactions, whereas real-world systems are often characterized by higher-order …

The structural architecture of international industry networks in the global economy

Globalisation continuously produces novel economic relationships mediated by flows of goods, services, capital, and information between countries. The activity of multinational corporations (MNCs) has become a primary driver of globalisation, shaping …

Modelling the social dynamics of contagion and discovery using dynamical processes on complex networks

Complex networks have been successfully used to describe the social structure on top of which many real-world social processes take place. In this thesis, I focus on the development of network models that aim at capturing the fundamental mechanisms …

Interactive discovery processes on complex networks

Innovation is the driving force of human progress. Recent urn models reproduce well the dynamics through which the discovery of a novelty may trigger further ones, in an expanding space of opportunities, but neglect the effects of social …

The role of tax havens and offshore financial centres in shaping corporate geographies: an industry sector perspective

The role of tax havens and offshore financial centers in Asia-Pacific networks: evidence from firm-subsidiary connections

Network dynamics of innovation processes

We introduce a model for the emergence of innovations, in which cognitive processes are described as random walks on the network of links among ideas or concepts, and an innovation corresponds to the first visit of a node. The transition matrix of …
