I was born in 1962, León (Spain). I am married with three daughters. In 1986 I obtained my Bachelor and MSc degrees from the Universidad Complutense de Madrid, and in 1990 I got my PhD from Washington University, under the supervision of Mitchell Taibleson and Guido Weiss. In 1990 I returned to Spain with a PostDoc fellowship (Reincorporación de Doctores) at the Universidad Autónoma de Barcelona. From 1991 to 2011 I was an Associate Professor at UB, where I am currently a Full Professor.

I have been the advisor of four PhD students.
