Current

I am Professor of Econometrics at Ca' Foscari University of Venice, since 2019 and Director of the Venice Centre in Economic and Risk Analytics VERA. I am a board member of the: European Society of Bayesian Econometrics ESOBE, the PhD program in Economics SSE, the International Master in Economics and Finance IMEF, the Master in Data Analytics for Business and Societies DABS and the Executive Master in Quantum Machine Learning QML.


Background

I was previously an associate and assistant professor at Ca' Foscari University of Venice, University of Brescia, University of Trieste, a research assistant at University of Padova, and a research fellow at GRETA Associates. 

I received a Ph.D. in Mathematics (Mathematical Statistics) in 2008, from University Paris Dauphine and CEREMADE-CNRS, a Ph.D. in Economics (Econometrics) in 2003 from the University Ca' Foscari of Venice, and a M.Sc. in Applied Mathematics from University Paris Dauphine and ENSAE. I have been a visiting professor at the University of Toronto, the University of Paris Sud, the University of Bristol and the University of Paris Dauphine.

Research

It is mainly in Bayesian analysis: Bayesian nonparametrics and semiparametric statistical inference, Monte Carlo simulation methods, time series models, text mining, graphical models, and network analysis. Below is a selection of my research projects.  Former and current Ph.D. students at this link.


I am currently an associate editor of Bayesian analysis and Econometrics and Statistics and a research associate of the centres ECLT, GRETA, member of the scientific societies ISBA, IMS, SSC, ES, SIS and SIdE; the scientific projects GRINS, HEIRS, HiDiNET, SCSCF, SYRTO and Systemic Risk Hub; and the scientific networks EABCN and ENBIS.

Other

Impact of my research: MathSciNet, ArXiv, GoogleScholar, SSRN, ORCID, Scopus, RePEc. Find me in the Math Genealogy Project with an Erdős number of 3. 

Spare time: I take pleasure in a variety of hobbies, including photography and exploring geology with a pleasantly ordinary proficiency. I often embark on geological explorations in stunning locations, accompanied by my family: Diana, Benedetta, and Riccardo.
