JP Carrascal is now a doctor!

The GTI member Juan Pablo (JP) Carrascal defended his PhD Thesis last Monday, January 26th, with the title “Aspects of personal information valuation in web browsing and mobile communication”.


Congratulations to JP, and his thesis advisors Dr. Rodrigo de Oliveira from Google and Dr. Josep Blat from Universitat Pompeu Fabra.

And thanks to the three members of the defense tribunal, Dr. Nuria Olivier, from Telefónica Research, Dr. Karen Church, from Yahoo Labs, and Dr. Davinia Hernández, from Universitat Pompeu Fabra.

It is worth mentioning that most of JP’s research work was conducted at Telefónica Research as part of a collaboration agreement between Telefónica and the GTI.

The abstract of the thesis:

“The goal of this dissertation is to provide insights into how web and mobile phone call users assign value to their personal information. Two user studies are presented. The first one used a refined Experience Sampling Method to obtain the the monetary valuation of Personally Identifiable Information (PII) of web users. We observed how the value of different types of PII compare, and reflected upon how these values relate to users’ concerns about privacy and monetization of their PII. The second study focuses on annotation of mobile phone calls, a process that involves selecting the information that the user considers to be the most important from the call. We found the factors that mainly influence the need of the caller to take notes. We also observed how the annotation needs and behaviors change over time. Finally, we evaluated different annotation techniques, including annotations made by context-independent observers. Our findings provide important insights for the development of automatic annotation tools, and also suggest the potential of crowdsourcing for finding noteworthy information from mobile phone calls.”
