During the early years of interne, he studied leading Spanish start-ups such as Olé, Barrabes, Teknoland, Netjuice, and served as consultant for companies like Telefónica, Telefónica Data, Microsoft, HP, CECA or the Norwegian Bank Association.

Professor Pérez maintains close relations with counterparts at the University of New York, Carnegie Mellon and MIT. He wants to see how companies use technology to relate among themselves and thus foresee the changes that these relations will undergo as new technological architectures emerge. 

This local approach to an international scenario from a business perspective rather than a technological one, is the DNA of Professor Pérez’s research activity. He is also using his experience at MIT to the full to develop a doctoral program in information systems for companies, at the Escuela Superior de Ingenieros Industriales de la Universidad de Madrid.
