He is on leave of absence from his previous appointment as professor of applied economics at the University of Vigo. Carlos holds a PhD in economics from the Autonomous University of Barcelona.

His research deals with enhancing the empirical evidence as well as methodological tools for the measurement and understanding of those issues.
