I work in the area of the analysis and characterisation of social structures and information dissemination in Online Social Networks. In particular, I study the personal social networks of online users (aka online ego networks) in Twitter and other social media and I analyse the impact of the structural properties of these networks on social processes such as information diffusion. The results of these data-driven analyses are used to create new context- and social-aware communication solutions for Mobile Social Networking applications, involving self-organising and ad-hoc networks based on direct wireless communications between mobile devices. Social information extracted from OSNs is used to predict users' behaviour in online environments and to optimise both mobile network protocols and applications, such as recommendation systems for mobile devices.
