I hold a Ph.D. in Demography from the University of California at Berkeley (2005). I specialize in economic demography, population aging, and mortality and health. I also have strong interests in demographic methods, indirect techniques, and regional and urban economics. Currently, my research is centered on two main topicis: a) studying how demographic changes are related to the changes in the labor market in developing countries. In particular, I am studying retirement trends, changes in occupation over time and across cohorts and how changes in the composition of the labor force impacts on the performance of different age groups; and b) small-area mortality estimation with defective data. In this project, we combine traditional demographic methods - death distribution methods - to bayesian statistics to produce estimates of life expectancy at the city level.
