I am ICREA Research Professor at Universitat de Barcelona since 2003. I work on gravitational physics, black holes and string theory. Since 2016 my research is funded by the European Research Council through the Advanced Grant "A New Strategy for Gravity and Black Holes".
In the last few years I have devoted some of my time to outreach. In 2018 I have published a popular book (in Spanish) where I've done my best at explaining to lay readers what every curious person should know about Einstein's theory of gravity and its most striking consequences: black holes and gravitational waves.
