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 primary author of three popular Stata commands providing a significant addition to Stata's capabilities in terms of estimation of stochastic frontier modelstwo-parts models and spatial models. Their popularity make me one of the top young economists in the world according to the Repec algorithm.
