Welcome to my website! I am an Assistant Professor of Econometrics at the Department of Economics and Finance, University of Rome Tor Vergata. My research interests are in both theoretical and applied econometrics. My ongoing research is mostly based on ideas arising from the theory of composite likelihood and robust estimation.

I am the coordinator of Simulation and Data analysis for the euFEM project at the Centre for Economics and International Studies and co-investigator for the Historical Household Budget (HHB) project.

Among the others, I wrote three popular Stata commands providing a significant addition to Stata's capabilities in terms of estimation of stochastic frontiertwo-part and spatial models.
