I completed my PhD in July 2012 in the Network and Operating Systems group at the Computer Laboratory in the University of Cambridge, supervised by Dr. Cecilia Mascolo. My PhD thesis is on the measurement and analysis of the spatial and geographic aspects of online social networking services. During my PhD I was involved in the the Spatio-Temporal Network Analysis project, in the International Technology Alliance (ITA) project and in the Wildsensing project.

In September 2012 I joined Google.

Short bio

I was born in Nicosia, a little and beautiful town in the middle of Sicily mountains. In 2003 I completed my secondary school and I was accepted by Scuola Superiore di Catania, an Italian university institution for higher education, where I won a 5-year scholarship to fund my studies.

In 2006 I was involved in some research programs with Agencia de Ecologia Urbana de Barcelona and Politecnico di Milano, both as a scientific consultant on complex networks algorithms and as developer. I received my Laurea in Ingegneria Informatica (comparable to BSc in Computer Engineering) in July 2006 with the thesis "Design and development of a health-care information system based on webservices" and I discussed my first Diploma Thesis "Video stabilization based on Scale Invariant Feature Transform" at Scuola Superiore in March 2007.

From July to September 2007 I worked as Intern Research Student at University College of London.

I received my Laurea Magistrale in Ingegneria Informatica (comparable to MSc in Computer Science) in July 2008 with the thesis "A self-organizing traffic model for urban networks".

In addition, I also received my Diploma Magistrale from Scuola Superiore di Catania in February 2009, with the thesis "Temporal Dynamics of Connectivity Traces: Chaos and Predictability in Human Behaviour". This work was done as Research Associate within the Computer Laboratory in the University of Cambridge, where Dr. Cecilia Mascolo was my Diploma thesis supervisor.

During 2011 I spent four months as Software Engineering Intern at Google Zurich, working with the YouTube Analytics team.
