I am an Associate Professor at the Department of Economics and Economic History of the University of Salamanca, the oldest of Spanish universities.  I hold a Ph.D. in Demography and an M.A. in Economics from the University of California at Berkeley, (legalized in Spain as "Doctor en Ciencias Económicas"). I did my major in Economic Sciences (with a field of specialization in Quantitative Economics) at the Universidad Autónoma de Madrid. Before that, I studied at the Instituto Ramiro de Maeztu in Madrid, where I prepared the International Baccalaureate Diploma.

My research activity focuses on demographic analysis, population and development, statistics and econometrics, having published extensively on those topics. I have organized this page according to the main research lines. You have access to each of them from the horizontal and vertical links.
