About Me

I am an Associate Professor in the Department of Economics and Business at the Universitat Pompeu Fabra since 2017. I received my B.S. degree in Economics and Quantitative Methods in 2003 and Ph.D. degree in Statistics in 2007 from Università di Firenze. I was a Post-Doc Research Fellow at NYU Stern until 2011. Over the years I studied, visited and researched at the University of Reading, Monash University, UCSD and EUI.

My research interests include: Time Series, Forecasting, Network Analysis, Statistical Computing, Empirical Finance.

Other Stuff


I am big fan of Linux and I like to code. Over the years I have developed a number of packages (in particular in R). Most of the code I develop can be found on my github page


While doing a post-doc at NYU I developed the vlab for on-line real time measurement and forecasting of financial volatility and correlations

Conference and Workshop Organization

Together with my colleagues at the Barcelona GSE I typically organize at least one workshop a year on themes in the neighborhood of econometrics and statistics within the Barcelona Summer Forum
