I am a PhD Student at UPC BarcelonaTech, researching in privacy and security, at the Telematics Engineering Department. In the past I was working as Operations Engineer at Google and as Support Engineer for Google Apps. I am particularly interested in privacy and security, and more specifically in analysing dynamics of online social networks and communities, and understanding the underlying structure of crowdsourced information. I have also a keen interest geographical services as I believe this are beginning to be an important part of any information services accessible online.
